How To Create An Old Camera In Blender?

This article shows you how to create an old camera in blender. The production process refers to an article by a Christian Wachter artist and introduces some new processes and complements the production techniques.
1. Modeling
Lens lens
The camera lens is a curved surface, but the arc surface created by the latitude and longitude ball will cause errors after subdivision because of the triangular surface. The more scientific method is to use a box, first add a subdivision modify and re-cast, and then scale an axis to get a lens arc surface with perfect topology.

Complex parts
For parts with complex structures and small parts, they are generally not subdivided, and it is enough to simply chamfer them with high precision. In order to save computer resources and processes, these finely divided parts can only be chamfered with high precision.

  1. UV
    Here are some of the next-generation game production processes, such as multiple objects sharing a set of UVs. In this way, whether you export the model to the third-party software to make the texture, or after the texture is created, import the blender and manage the texture material in the blender.
  1. Texture
    The texture is selected to use the substance painter. When drawing the edge wear, in addition to using the SP's own program texture, some more serious wear is manually drawn in the sharp part of the model, and the gradient wear of the gear adjustment knob is defined. .
  1. Material
    What is worth noting in the material is that because the camera lens has an anti-reflection coating, the reflection of the lens is blue-violet. The top half of the picture as below.
    In Blender, I tried to simulate a dispersive material using the red, green, and blue color overlays, but the effect was unsatisfactory and the rendering points were extremely large. As shown in the lower part of the figure below.
    Finally, use a Fresnel as the basis of the gradient, change it to a blue cyan gradient, and mix it on the surface of the gloss to simulate the material of the camera lens.
  1. Synthesis
    After De focus rendering is complete, select to blend in Blender, as shown in the two images below, and change the gradient on the Z channel to control the post-defocus effect. One makes the rear part of the camera slightly out of focus, and one makes the floor behind the camera seriously blurred out focus.

Deformation and hue
Finally, add a little lens distortion to it, and use the color balance node to give it some stylized color.

Blender Tutorial: To Create A Wild Jungle(2)
In the previous article “Blender Tutorial: To Create A Wild Jungle”, we have shown the production of the scene model part in Blender, and then let’s starts the part of the texture. I hope to help you with your production process. Thanks again to the author of this article, 3D artist Leo Lee. Texture Material Shader can choose ‘Principle BSDF’, which is a kind of useful in Blender, and supports some commonly used texture mapping parameters. UV treatment before mapping. Switch to Edit Mode, select all faces, and select Unwrap UV - Smart Unwrap in the mesh menu. Since the model here is an irregular model, there is no need to manually process the UV. Then add these texture options in Node, select Image Texture, and import the corresponding material map. In Basic Color, you can choose a ground material that looks moist. Connect to the Basic Color and use the Multiply node to make the color darker. Add the Roughness map again, and also use Multiply to control the intensity of the reflection. Then import the Normal Map and Height Map in turn, and link to the Normal of the Principle through the Bump node. The size of the texture can be controlled by adding a Mapping node to control the angle, position, and size of the texture. In order to make some changes to the surface, another map similar to grass is added. The purpose is to add the raised part to the material of the grass according to the undulation of the ground, and the wetland material is recessed to make the ground appear more real. So how do you mix two different materials according to the fluctuations of the surface? The node that needs to be used here is called Geometry. After adjusting the black and white over with the color ramp, the convex part is set to white, and the concave part is black, thus distinguishing the surface according to the geometric structure. Start and volt, then mix the two materials together through the Mix Shader. Then switch the node wrangler to the mix shader to see the mixed effect and use the same method to attach materials to other objects. What needs to be used here is the transparent method of material. First, you need to select a PNG or TGA transparent material map in the image texture, then use the Transparent BSDF to link it with the Diff BSDF through the Shader Mix Alpha, you can follow the Alpha The parameter hides the black part of the transparent material. In the same way, the leaf part of the tree is also made of material. If the leaves and the trunk are in the same Object, then in the edit mode, the trunk and the leaves can be separated by the separate function, and then the new material is assigned to the selected area. In the same way, small plants are also made of transparent materials. Rendering Before rendering, you need to adjust some of the following parameters. We choose the GPU rendering mode, which will be faster than the CPU. Then set the length and width pixels to increase the rendering detail to 100%, the default is 50%. Transparency is activated in the film menu below, and the background can be transparently processed after rendering. If you want to blur the foreground, you can select the camera, and then set the distance of the focus in the depth of view, which can better render the spatial sense of the picture. Here, some effects are processed on the rendered image, similar to the film and television in the VFX workflow, to superimpose some fog and Sun Bean effects and color adjustment according to the space of the object.

Blender is a powerful and free open-source application, especially in 3D scene construction, rendering, and special effects, compared to similar software has obvious advantages. As the leading service provider in CG industry, Fox Renderfarm supports both blender rendering, 3ds Max rendering, Maya rendering, C4D rendering, Clarisse rendering, SketchUp rendering, etc.. This article wrote by 3D artist Leo Lee, will show you the potential of Blender to quickly create scenes and texture rendering, and will show some experience and hope to help your production process. Let learn how to create a wild jungle in the blender. Add a Plane to the view, the size can be larger, switch to Sculpt Mode. It is similar to some familiar engraving software, such as Zbrush, which can choose different brushes to process the model. Check Dyntopo at the menu (no need to manually subdivide the model), and select ‘Constant’ for the detail mode, and check the smooth shadow. As shown in the figure below, when the model is engraved, the system automatically subdivides the number of faces. Here are a few other ways to create terrain. Use Subdivide to subdivide the surface as follows: subdivide into 50-100. Then add a black and white material through the Displacement Modifier in Blender, similar to the Height Map, which can be hand-painted in PS or downloaded. Click Add Material Map to import the material. The strength of the ground fluctuations can be controlled by adjusting the parameters. Then add Subsurface Modifier to smooth the surface. In addition, if you want to adjust the terrain manual area, you can activate the area control button below, the middle button wheel to adjust the area range, select a point to drag and drop. Here is a finished terrain. The next step is to add some decorations to the terrain, such as trees, grass, stones, and medium-sized plants, to create a more realistic picture. The model of several trees is imported into the scene, as shown below. It can be imported via ‘append’ ‘Import’. Append can only add original Blender files. Import can import some commonly used 3D files, such as 3ds, FBX or OBJ. Previously, the terrain and trees were layered. The layering function in Blender can manage the model very effectively, compared to the layer function in PS. Select the model, ‘M’ to move the active model to any layer, press the number keys to move to the corresponding layer. Hold down the Shift key to select multiple layers at the same time to display the contents of their layers. The imported trees are arranged in order according to space and the composition, and then the position is selected to place the camera. As shown below, Below are the layers of stones and grasses and small and medium plants. Due to the large size and a limited number of trees, manual placement can be used. But like those small and large objects, you can use the ‘Particle’ series to let Blender randomly place small objects according to the range we set. As shown in the figure below, first switch to ‘Weight Mode’, you can first lower the transparency, then draw the range of the area where you need to place small objects on the terrain, blue is the vacant area, gradually yellow, and the dense area is excessive. Then switch to "Particle System" in the menu on the right, click the Add button, here is similar to the step of adding material to the object, and the material here is the object that needs to be placed, the first layer I chose the grass, can pass the view The button hides other objects. Activate the data indicated by the arrow in turn. Each of the previous objects must be Ctrl+G in advance and merged into their respective groups. Then here Dupli Group chooses the grass group. The values in the red box are some random parameters for which various adjustment objects are placed, such as orientation, size, rotation angle, and so on. If you adjust the density and length units more deeply, you can also select the corresponding Group in turn. In the same way, the stones and other vegetation are also brushed in. As shown below. After the addition of plants and ground, the contents of the camera lens are richer.
