Fox Renderfarm, a powerful but affordable cloud render farm, shared this article from 3D artist Qixi is a cup and grape made by Octane for Cinema 4D. We have already talked about the glass making process in the previous article, and the next is grapes production and rendering analysis.

The grape model is very simple, you can make one first, then put it in Unfold3D to place the UV, and then copy and place it.

The texture of the grape is made in Substance Painter. It should be noted that the surface of the grape will have a layer of dust-like texture. After testing some materials, 5 textures are output to simulate the effect of that layer.

Since the grape is a translucent object, it can be adjusted based on the 3S material. And increase the diffusion and roughness, after adjusting the effect is as follows,

Once the texture of the grape is satisfactory, you can then copy it and place it on the plate. To save time, you can create a cylinder as the emission range of the particles and a circular patch as the base. After adding random size changes to the grapes, use dynamic simulation to place the grapes on the plate.

In order to make the effect look more natural, I copied some grapes and placed them on the table next to the cup. Now I can test the rendering.

After the test, I feel that the glass is a bit too smooth, and a little roughness needs to be added. Then added a roughness texture to the glass.

After testing the rendering again, I feel that the picture is bright, which may be due to HDR problems. Finally, replace an indoor HDR texture and turn the power down.

The current display looks better, but the background part is still a bit far away. Now add a wall to the back of the glass. Does the effect of the glass material look better?

The overall picture still lacks some details, you can add an older texture to the wall, and test the rendering again (note that the texture is proportional to the size).

In order to enrich the lighting details, a flat can be added to the top of the cup to make the roof. Change the focal length so that the focus is on the cup and increase the environmental fog. The color of the fog changes to yellow.

Octane for Cinema 4D Tutorials: Making Cups and Grapes (1)
Fox Renderfarm, a powerful but affordable cloud render farm, shared this article from 3D artist Qixi is a cup and grape made by Octane for Cinema 4D. This article analyzes the scene's modeling and rendering. First of all, this is not an original project. The 3D artist refers to the conceptual diagram above, and he wants to restore the glass in the picture. Then we shared how to make them work with Cinema 4D and Octane renderer, and shared the production process of the glass filled with grapes in the concept map. Reference The difficulty of the glass in the concept map is divided into three points: 1. Round glass notch 2. The middle of the cup handle is a six-diamond structure 3. Rendering of the diamond-shaped bump material of the cup body Modeling First, put the concept map into Cinema 4D as a reference. Use the cylinder to create the part of the glass cup handle. You can adjust the overall shape first and then add the subdivision adjustment. To adjust the details of the bottom of the cup, you need to first seal the bottom of the cup to make a slightly convex shape. The glass is transparent, but its structure is very complicated. In particular, there will be some subtle changes in the shape of the interface, and it is necessary to constantly subdivide and observe the structural changes and continuous modifications. The structure of the model itself must be achieved, and the final effect will be more realistic. Next, the part of the cup body is made in the same way as above. Special attention should be paid to the position where the cup mouth is recessed. If you want a sharper edge, you need to add a line to the edge to ensure that the shape is maintained after subdivision. In order to make the structure of the six diamonds more obvious, the position of the handle is increased by adding lines on both sides of the rhomboid to maintain the shape. The other lines need to be treated with this additional line. The diamond-shaped convex surface of the cup body is not well controlled if the model is made directly. So prepare to use the texture to make the diamond convex surface, you need to do UV before texture. UV uses another production called Unfold3D, which is very fast and convenient and can improve work efficiency. However, if the diamond-shaped convex surface is simply drawn using Photoshop, the effect will not be too good. So I decided to make a model of the diamond-shaped convex surface and then baked the bump texture to use in the diamond-shaped texture part. The rhombus gives a white material and adjusts the effect after adding lights. The white areas are convex and the black areas are concave. Export this texture to Photoshop. The next step is to use the glass texture of the Octane renderer to link the previous map to the Displacement Maps and put it on the cup for testing. The effect is closer to the concept map. Create a flat surface to place the cup on, and use the basic texture of the Octane renderer to add wood grain material. But now the background light is excessive, but the reflection of the cup body is not strong enough. Add an area light to make the reflection brighter, and change a slightly darker HDIR to highlight the main body of the cup. After adjustment, it is already closer to the concept map.

Octane for Cinema 4D: To Make A Fantasy Forest Scene
Octane for Cinema 4D: To Make A Fantasy Forest Scene
Fox Renderfarm, your TPN-accredited cloud render farm, organizes this sharing experience comes from the 3D artist Luren4796 for you. The main software used is Octane and Cinema 4d. Luren4796 share us the entire production process about this fantasy forest scene. I hope you can learn something. This fantasy forest scene was inspired by the artwork of other artists. Luren4796 took inspiration from it and wanted to make a fantasy forest with a metal altar in the middle of the forest. So he combined the two works of art to conceive a unique artwork. The reference artworks Modeling The modeling of the main body ball is very simple. It mainly uses a plug-in called Trypogen. This plug-in is very good. It can easily change the basic sphere of Cinema 4D into other arbitrary shapes. I suggest you try it. The ring around the sphere is also very simple. It is also modified using the circle that comes with Cinema 4D. The more convenient point is that the UV of the built-in model is already split, and you can use it with a slight modification. UV uses a software called RizomUV, which can quickly place the UV in the way you want. If the model of the altar is split, it is also quite simple. The only trouble is the edge wear on the base. This is a deliberate use of a broken plug-in, which can quickly create broken edges on the cylinder. Scene making First, a displacement map was used on the ground, and then, the AO discover, replace, bump and specular map was used. Then add an HDIR to the scene, and a blue fill light on the right, and an increase on the left. An orange fill light. An orange light was added directly in front of it to add color to the subject. Textures for ground use Light source position The tree in the scene is made of Forester Tree Library. In order to have a better final effect, you can place the camera first, and make some optimizations and adjustments according to the foreground in the lens. The foreground looks relatively empty. After consideration, some stones and stumps made in the previous project were added as decoration. Add some decorative flowers and trees according to the lens again, still made with Forester Tree Library. Now you can see that the background and the sphere and some models of the altar are all made. The texture of the ground looks good. In order to better integrate the ground and the altar, you can try adding texture to the altar to test the effect. But the foreground still looked a bit monotonous, so some water elements were added to the grass, and the prominent part of the altar was modified into a gem. And add water and gem materials to self-illumination to make the dream effect look more prominent. Particles and fog The particles use the default particles, which increases the number and reduces the speed, and adds a dry wave to increase the randomness of the particles. Change the shape to a sphere and add a glowing material. Create a random color node connected to the gradient (color setting: same as the scene orange and blue) to make the rendering look more natural. Added a layer of fog behind the bushes to make the scene feel more volume. Texturing The texture in the middle of the sphere uses a sub-surface scattering associated with the metal layer. The color of the Transmission is adjusted to blue, which increases self-illumination and adds a layer of scratches on the bumps. The outer ring part is painted by hand. Increasing roughness increases bumps and specular reflection. The general effect is as follows: After testing the rendering, I felt that the picture was not rich enough, so I added 2 butterflies below the ring. Adjusted reflection, refraction, and saturation and color temperature in PS after layered output. And here is the final rendering,

Using Octane for C4D to make a natural scenes (2)
Using Octane for C4D to make a natural scenes (2)
As the leading Cinema 4D render farm in the CG industry, Fox Renderfarm will continue to show you how to use Octane for C4D to make a natural scenes. In the previous article of production process, the forest was already done, and the part of the road was relatively simple, and the road model in the C4D preset library could be used directly. After rendering, you can see that the overall picture is already there. But there is a black color at the junction of the ground and the sky, because there is no model occlusion in the distance. Then this place needs to add some fog to block the black place. And compared with the real environment, there is still some environmental fog and depth of field, but also need to add some light and shadow, the part of the sun needs to be adjusted. If you want the current environment and the reference map to look similar, then the angle and strength of the light source need to be adjusted to add fog. Reduce the density of fog and increase the sense of the atmosphere. After the rendering, you can see the sun through the woods. Now that the woods look a bit narrow, you can increase the length of the woods and increase the number of trees to make the forest look denser. Using an Octane camera, with a suitable angle, you can see that the overall light and shadow effect is great. But now there is still a problem, the tree in front of the camera is a bit dark because of the backlight. This requires adding a slightly brighter HDIR to the entire scene. Rendering again, you can see that the entire scene is lit, and the light looks very good. It can now be seen that the reflection of the road is too strong and the color is also problematic. Then you can adjust the road material, reduce the reflection, increase the roughness, and add some dirt to the Shader's Amount layer. Now you can see the reflections and bumps on the road. If you want to be more realistic, you can add some old textures and stains to the road. The scene has been basically completed, you can compare the effects in the reference. Now you can add a car and render again to see the final effect. This workflow only explains how to make an outdoor scene. I hope you can learn something from this article.
