However, this approach has some limitations: The scene graph must be adapted, which leads to confusing layouts. Using RTT (render-to-texture) allows to easily scale rendering quality (resolution, LOD, lighting complexity) for adjustable performance. Cube: The render texture is a cube map. Instead of rendering/drawing/painting directly to the screen, the example code uses a technique called "render to texture". In conclusion, 3D rendering is a remarkable process that transforms virtual objects and scenes into visually stunning images and animations. To use this framework you need to assign a Material to the Custom Render Texture asset. You just have to create a new asset using Create > Render Texture and then assign it to your camera. When we bind the render target to be drawn onto, we will actually be drawing on the texture that the render target points to. Rendering to a Render Texture.

In ViewNode: create a render pass: There is a lot of shared boilerplate between different Node s. You could probably use OnRenderImage. Rendering to texture, or "texture baking,” allows you to create texture maps based on an object's appearance in the rendered scene. The advantage of using textures is that the render output is stored inside the texture image that we can then easily use in our shaders.
