Cinema 4D Tutorial Making a Ring Full of Small Balls -18

C4D is a 3D software developed by MAXON in Germany. Its interface is simple in 3D production software, which is easier to learn and use for Maya and 3ds Max. It can model material, light and bind animation rendering and other functions, and it has powerful built-in film and television VFX, animation design, industrial medicine, physics, etc. C4D can be used in many industries. It belongs to the same kind of software as Maya and 3ds Max, but it has been on Apple computers in the early days. In recent years, it has been widely used in WINDOWS.

Fox Renderfarm, the best cloud rendering service and render farm online, will introduce how to use C4D to make some shapes full of rings in this tutorial. The reference work was originally made by a 3d artist from Behance.

Modeling

In the ring above, you can see that it is mainly composed of three parts, a small ball filled with the ring, a layer of spiral shape outside the ring, and scattered small balls. The outside will make these things step by step. First of all, I will make a small ball full of rings. This requires first making a ring for the shape.

  1. First make a Circle, click the C button to convert it into an editable object, and compress the Circle into an ellipse.
  2. Add a second Circle and use the Loft modifier to make the two circles into a circle.

Sphere Adding

First add three spheres of different sizes, which can be arbitrary. Then add Cloner, then place the three spheres under Cloner, change the Mode under Cloner to Object, drag and drop Sweep under Object, and change the Mode of Distribution to Volume.

The three small balls have generated a ring full of small balls based on the ring, and my Count value is 1000.

Now you can add dynamics. Right-click under Cloner and select Simulation tags to add Rigid Body. Note that in the Collision property of Rigid Body, Inherit Tag selects Apply Tag to Children, and Individual Elements selects ALL.

Right-click on Sweep and select Simulation tags, and add Collider Body. Select Static Mesh in Collision's Shape under Collider Body.

Now play the animation, and you can see that the ball will fall down due to dynamics. I constantly test the drop of the balls and change the number of balls in the Count in Cloner until the balls fill up the ring.

Now you can see that the ball is basically filled, and then start to make a layer of the spiral shape of the outer ring. I hide the ball first and add a spiral shape. Add a Spline Wrap to the spiral shape, then add the line to the Spline of the Spline Wrap, select Y for Axis.

Select the spiral shape to convert it into Current State To Object, and get a new editable spline. Hide the most recent backup, close the new spiral, and adjust the smoothness.

Re-create the two rings and adjust them to a larger one and a smaller one, then select the two circles and right-click-Connet Objects+Delete, and then move the axis to the middle of the two rings.

Add a Sweep, and then put the previous ring and spiral under the Sweep. If the staked object is thick, you can change the thickness of the object by directly changing the size of the ring.

Display the previous balls to see if they match, if they don’t match, just adjust them again.

Rendering

I made a simple scene for rendering. The light used a simple three-point light source: left and right cold and warm light plus the main light source at the top, and found a suitable position in the scene. The main light source brightness is 100.

I added a light again, placed it behind the model, and lowered the intensity of the light. I copied a clone again, changed the mode to grid arrangement, and copied the collision body label of the shell to a backplane, and played the animation to get the scattered spheres on the ground.

Now set the shader for the ball. I used a simple shader, added a Diamind effect to it, and reduced the width of the highlights.

What are topology and retopology of 3D models?
What are topology and retopology of 3D models?
IntroductionIn this article, the best CPU & GPU render farm and cloud rendering services provider, Fox Renderfarm, will tell you what are topology and retopology of 3D models and how to retopologize a model in C4D. When using 3D software for modeling, everyone has their methods and processes, and the construction of the same model will vary from person to person. But what makes a good model? If a model is poorly structured, how to optimize it? These problems involve the topology and retopology of the model. With these questions, let's take a look at what problems we need to pay attention to in the modeling process.!What Are Topology And Retopology Of 3D Models-1 What are topology and retopology?Traditional topology is a subject related to mathematical geometry, but we discuss the topology concepts related to 3D modeling here. Now let's understand the topology, and then the retopology.•TopologyWe know that a model is represented in 3D software by a series of surfaces combined at different angles. In my opinion, the topology of 3D modeling is the structural distribution of the surfaces of a model, which is wiring. There are so many ways to combine surfaces when trying to represent and make a 3D model. For example, look at the cube below, although the distribution of surfaces is inconsistent, the appearance looks exactly the same.!What Are Topology And Retopology Of 3D Models-2Each model has its own topology. Some are industrial models exported by industrial design software, such as ProE and SolidWorks; some are made by scanning or other reverse engineering; some are the common model format, such as *.obj, *.fbx, etc. that are exported by different 3D software. Here comes a problem: even if it is the same model, the topology generated in different ways can sometimes give us troubles in the subsequent animation and reprocessing.•RetopologyOnce you understand topology, retopology is straightforward. It is about reconstructing and representing the same model, using a better topology-a more appropriate distribution of surfaces.!What Are Topology And Retopology Of 3D Models-3When retopologizing a model, it will pay more attention to using an appropriate number and size of surfaces to represent a model. And if you need to make point level animations (character’s body animation, cloth, etc.), you should pay more attention to building out some ring and loop structures, so that you can deal with the unsatisfactory animations (such as model collision, overstretching, etc.) produced after extrusion and stretching the surfaces.!What Are Topology And Retopology Of 3D Models-4 What is a good topology?First of all, making a good model should try to avoid triangular surfaces and n-gon surfaces connected by more than 5 edges, and try not to make poles with more than 5 edges in important positions. Otherwise, crossed surfaces or unsmooth effects may appear in these places when making subsequent point level animations. For example, for models designed by industrial software, there are a lot of triangular surfaces after the format is converted, and it will be troublesome to create chamfering effects or add subdivisions for these edges.!What Are Topology And Retopology Of 3D Models-5Secondly, a good model should have a good edge flow, which is not only convenient for selection, but also offers a good tension during subsequent animation production.!What Are Topology And Retopology Of 3D Models-6Some positions that need to be animated, such as eyes and mouth, should be modeled with appropriate structures and enough surfaces to support the animation details.!What Are Topology And Retopology Of 3D Models-7!What Are Topology And Retopology Of 3D Models-8 What are the benefits of retopology?•A good topology can make the animation betterModels with reasonable structures will show better modeling when it is squeezed and deformed. As three cubes with different topologies that are shown below, some surfaces of them will be torn after they are twisted to a certain degree.!What Are Topology And Retopology Of 3D Models-9•Models with good topology will be reworked more efficientlyFor these models, when we want to add chamfers or add some details to them, we can quickly modify a specific part of the surface. However, for models with unsatisfied wiring, we can only add details by increasing the distribution of modification lines again, which will be inefficient for some complex structures.!What Are Topology And Retopology Of 3D Models-10•Retopology allows for faster mappingFor the production of some mapping, the stretching of UV is needed. If the density of different areas of the model is so different, or if there are both triangular surfaces and N-gons, it will make our work very tedious. So after retopology, the model can make the production and performance of material mapping become more effective.!What Are Topology And Retopology Of 3D Models-11 What are the ways of retopology in C4D?There are not many ways to retopology in C4D, but we usually use other software's retopology function to improve the modeling. I will introduce 3 methods of retopology as follow.•Remake some parts of the modelFor some parts with simple structures, it can be made directly through geometry, and then connecting these parts to the model.!What Are Topology And Retopology Of 3D Models-12For some surfaces, shrink wrap and polypaint can be used to retopologize parts of the structure. For example, use shrink wrap to fit some evenly distributed surfaces to the model, and then optimize and merge the structure.!What Are Topology And Retopology Of 3D Models-13•Using volume objectsIn the version after R20, using volume objects can directly generate a model with relatively uniform wiring, but there is not much room for manipulation, and sometimes the edges are not ideal. And if you want more details, you have to produce a lot of surface models.!What Are Topology And Retopology Of 3D Models-14•Using QuadRemesherIn addition to the two methods above, we can also use the QuadRemesher plugin for retopology. For this plug-in, the developer has only released and tested the version applied to Maya and 3ds Max before. Recently, the C4D version has finally come out. I can say that C4D did not have an easy-to-use retopology plug-in before, so the release of QuadRemesher allows us to save more time. Its use is also very simple. Only need to adjust the number of generated surfaces, size and density, you can directly get an ideal model.!What Are Topology And Retopology Of 3D Models-15 ConclusionRetopology can help us get a more satisfied model, but how to build and process a model depends on our production needs. Here is a good guide article for you to know more: 3D Modeling Tutorial: Handheld Fan. If you want to create your work using the shape of the model only, then you can just create the shape that meets the needs. If you want to make mapping, animations and others for the model, then you should add lines appropriately according to the requirements of the animation. The model structure can improve the efficiency for the later stage.After the model is built, if you are not too pleased with the effect of C4D rendering, you can look for a cloud rendering farm like Fox Renderfarm to help you render. Hope this article helps you!

C4D Tutorial: Using Field Forces to Create Diamond Dispersion Effect with Particle Motion on the Surface
C4D Tutorial: Using Field Forces to Create Diamond Dispersion Effect with Particle Motion on the Surface
So today we'll use C4DR21's Field Forces to create this diamond dispersion effect with particles moving on the surface! Let's Start MakingIn C4D, first create a new sphere, segmentation can be appropriate to increase a little, type selection for Lcsahedron, Radius value slightly changed a little smaller: !Field Forces to Create Diamond Dispersion Effect 2Add a Disolacer deformer to the sphere, add a noise wave to the shader, and the global scaling of the noise wave can be slightly larger to create this bumpy sphere effect:!Field Forces to Create Diamond Dispersion Effect 3Then add a Subdivision Surface, Subdivision Editor and Subdivision Renderer under Object are set to 1:!Field Forces to Create Diamond Dispersion Effect 4Next is a new feature of C4D R21, we add a Volume Builder to the object. C4D R21's volume generation has added a new mode of vector, it can convert the object directly into a vector, we increase the accuracy of Voxel Size a little bit:!Field Forces to Create Diamond Dispersion Effect 5Next, create a new Random Field and drag it into the volume generation. By default, random fields are created in a cubic space:!Field Forces to Create Diamond Dispersion Effect 6First we can change the creation space to below the object, representing the creation of vectors based on objects:!Field Forces to Create Diamond Dispersion Effect 7But now the direction of the vector is not what we want, because by default it is the direction of the object normal, and for the sake of observation I have slightly enlarged the scale of the random field here:!Field Forces to Create Diamond Dispersion Effect 8Back in Volume Builder, we change the blending mode of the Random Field to Cross, so that the direction of the vector is the direction of the surface to which the object is attached:!Field Forces to Create Diamond Dispersion Effect 9But now the vector is not used, we need to convert it to a field force, so create a new Field Force and drag the volume object into it, selecting the type as Volume Object:!Field Forces to Create Diamond Dispersion Effect 10Now you may not see any effect, you need to create a new Matrix, with Subdivision Surface as the object Object. Distribute it as a surface is fine, then let the matrix generate TP particles, the number can be slightly more:!Field Forces to Create Diamond Dispersion Effect 11By default, the field force does not affect the particles, so you need to do some simple settings. First of all, create a new xpresso tag, and create a new particle transfer in the TP particle creation body: then add a PForce object in the TP dynamic item, which is also a new feature of R21, and then drag the field force into the PForce object, so that the TP particles can be affected by the field force:!Field Forces to Create Diamond Dispersion Effect 12Clicking on play will reveal that the particles will fly out after a period of motion:!Field Forces to Create Diamond Dispersion Effect 13This is because the mode of the field force is not correct, so change the mode of the field force to set the absolute rate, and then increase the intensity a little, you can see the particles hovering along the surface of the object:!Field Forces to Create Diamond Dispersion Effect 14Next we add Thinking Particles to the matrix, change the Limit to From End, then set the Amount to 50, and then play to see the beautiful circling lines:!Field Forces to Create Diamond Dispersion Effect 15!Field Forces to Create Diamond Dispersion Effect 16!Field Forces to Create Diamond Dispersion Effect 17I think the number of particles seems to be a little bit more, so I changed the number of particles to a smaller one:!Field Forces to Create Diamond Dispersion Effect 18When we feel it is almost ready, we can first convert the trace object to an ABC file, make a copy of the subdivision object, and back up the rest and turn it off:!Field Forces to Create Diamond Dispersion Effect 19Now the lines are appearing from nothing, we want it to be the same as the reference case that is always there, so we can offset a little bit in the animation of the ABC file, and then change the frame duration to 180 frames: !Field Forces to Create Diamond Dispersion Effect 20The next step is simple: create a new gem, resize it appropriately, and add a chamfer deformer to it. Create another larger gem, then add a lattice to this gem, with smaller cylinders and spheres. Rotate the angle of the lattice and the sphere, and put them into a group:!Field Forces to Create Diamond Dispersion Effect 21Set the keyframe in the group's rotation , remember to change the curve to linear, and then you can move on to the rendering.Open Redshift, set the render size, first I still use the linear space, and then the scene does not need global lighting, so turn off the GI. Then I did not improve the number of reflections and refraction, because I compared and found that the default parameters seem to look better: create a new HDRI ambient light; you can try more mapping, preferably with the color of this dispersion so the effect will be better:!Field Forces to Create Diamond Dispersion Effect 22Add the RS object label to the sample bar, select the curve mode for the hair on it, and then properly adjust the curve to control the thickness of the beginning and end of the sample bar:!Field Forces to Create Diamond Dispersion Effect 23!Field Forces to Create Diamond Dispersion Effect 24Next is the material, first use a gradient node to connect the material of the sample bar to the color of the luminescence. Change the mode of the gradient node to Alt. I gave the intensity of the glow to 10. Because we are rendering hair, we can give a hair position node to connect to the gradient, so that the hair will have a little gradient according to the position color:!Field Forces to Create Diamond Dispersion Effect 25!Field Forces to Create Diamond Dispersion Effect 26The material of the sphere is nothing special, it is an ordinary dark green reflective material: the next is the material of the jewel body, in fact, is a glass material, I slightly gave it a little reflection of the rough, and then the dispersion I adjusted to 2:!Field Forces to Create Diamond Dispersion Effect 27In the optimization options deselect Weak internal reflections. Then in the lighting details, change whether to affect refraction to always:!Field Forces to Create Diamond Dispersion Effect 28The final lattice material is very simple, is a common luminous material, and then use a gradient color to control the color of the luminous and transparent channel. Sampling settings due to the glass and there is dispersion, my maximum and minimum uniform sampling 256/16, other local samples are 512:!Field Forces to Create Diamond Dispersion Effect 29 The Final ResultFinally, add some glow and see the effect:!Field Forces to Create Diamond Dispersion Effect 30Fox Renderfarm hopes it will be of some help to you.

C4D Tutorial: How to Animate a Square Collapse
C4D Tutorial: How to Animate a Square Collapse
The best cloud rendering services provider and C4D render farm, Fox Renderfarm, will share with you a C4D tutorial from 3d artist Flynn. This tutorial uses the C4D R20 version, if using the previous version, you need to adjust some relevant parameters. The tutorial involves a lot of techniques, you can understand and deepen the use of various commands through the case. IdeaThe idea of production will be more important than the learning of operation, so we will talk about the overall thinking process first. Firstly, the first idea was tested. I created a Cube, a Taper effect, and added a Step effect in Falloff. Then use the Cloner to scale to make a rotated column, and then perform a circular radial clone on this basis. AT last, I got a circle, but the circle was not perfect, especially the joint was incomplete, so the method was abandoned.!C4D Tutorial How to Animate a Square CollapseThe second idea is to directly use a disk to operate the surface on the disk, and this method constructs a suitable figure, but the control of the figure is a problem, we can only operate the whole figure but can not operate on a single column, and each part of the axial direction is located in the center, and can not make the feeling of turning.!C4D Tutorial How to Animate a Square CollapseNow there is a problem, in order to better control the animation of the graphics, we need to use the cloned graphics, and directly cloned graphics can not become the desired shape, and directly make the shape can not be very good control, so we need to change the thinking, use cloning to create objects, and then use other methods to make the disk effect. So, using cloning, and then deforming the cloned object, we can achieve the desired effect. ProductionFirstly, to realize the animation control of a column of cells around, so we first make a cell clone object, and directly use the linear mode to create a column of element objects.!C4D Tutorial How to Animate a Square CollapseThen add a Plain to the cloned column element, and adjust the displacement scaling rotation attribute under Parameter. Also add a Field effect in Falloff, and adjust Field/Field to X-. Drag the Linear Field to see the animation effect.!C4D Tutorial How to Animate a Square CollapseIn order to rotate the elements more closely, we also need to adjust the axial position of the basic cube. Select Cube first, then adjust the pivot position in Spline/Axis Center.!C4D Tutorial How to Animate a Square CollapseAfter making the control effect of a unit, we clone it into multiple copies and stack it together evenly.!C4D Tutorial How to Animate a Square CollapseAdd a Spline Wrap and then add a Circle to constrain it to Spline Wrap/Object/Spline. And change Axis to +Z. A new Null is formed by the Spline created and the null made previously.!C4D Tutorial How to Animate a Square CollapseOne thing to note here is that the scope of influence will be changed according to the size of the object at the same level, which will cause the shape to change with the movement of the linear domain. Therefore, we need to check the range box of the deformer to maintain the shape of the shape. When the scope box is fixed and the number of clones is changed, the objects outside the scope box will not be affected by the deformer, and we need to re-fix the scope box.!C4D Tutorial How to Animate a Square CollapseThen we can adjust the size of the disk by changing the size of the disk, and then set the keyframe to the Linear Field. We can get an effect from the outside to the inside.!C4D Tutorial How to Animate a Square CollapseThen the most critical step is that we don't want the motion of each column to be synchronized. At this time, we can use the random effector to achieve this out-of-sync effect. We can use the random effector to make a random offset of the key frame of the motion of each random Linear Field to get the final effect.!C4D Tutorial How to Animate a Square CollapseThe above is all about how to animate a square collapse with C4D. We hope you can learn something from this article.
