Compositing Rich Pixel Renderings ❚❘❘ Now you can apply effects to the selected object in your rendered scene. Compositing Rich Pixel Renderings Once you create a rich pixel rendering and import it into Combustion, you can use it in composites as a layer. This section describes Z Depth transforms, shadows, and camera matching-effects you can create without using 3D Post filters. 3D Post filters are described in Using 3D Post Filters in Combustion. The following table lists the G-Buffer channels used for Z Depth compositing, shadows, and camera matching. To use these compositing effects, make sure you save these channels when you render the rich pixel file. Channel Z Material Effects Object UV Coordinates Normal Non-clamped Color Coverage Node Render ID Color Transparency Velocity Sub-pixel Weight Sub-pixel Mask Z Depth Shadow Camera Transforms Matching Yes Yes No No No No No No No No No No No Yes Yes No No No No No Yes No No No No No No No No No No No No No No No No No No Z Depth Transforms Use Z Depth transforms to make flat video layers appear to move within the 3D space of a rich pixel image. Note: This feature requires that you render the Z (Z Depth) channel as part of the RPF or RLA file in 3ds Max. To move layers in Z Depth: 1. In the Workspace panel, click the rendered layer to select it and display the Composite controls. 2. Click Layer. 3. In the Layer controls, enable 3D Depth. Note: When 3D Depth is enabled, you cannot rotate the rich pixel layer in X or Y. 4. Use the Z Offset field to adjust the offset between the Z scale in the RPF or RLA file and the Z scale in Combustion. 5. Use the Z Scale field to adjust RPF or RLA files where the Z range is very large. When you move or rotate any layers in the composite, they appear to move within the 3D scene. 883
