Mobile Compositor Effect Demo Using Raster Shaders
By

Warm and crisp on the edges. A bagel with a bit of bite.
Summary
This demo project demonstrates how compositor effects can be implemented on the mobile renderer using a raster shader, as an alternative to the compute shader approach used in Forward+. It reads from the depth buffer and outputs depth data into the color buffer, effectively creating a depth debug mode. The project uses GDScript and supports both Mobile and Forward+ renderers.

· 5 pulledThis demo project shows how compositor effects can be used on the mobile renderer using a raster shader.
This is more limited than the compute shader approach possible in Forward+.
Compute shaders can't be used with the textures for our main render target due to limitations in the usage flags.
This is an example that reads from the depth buffer and then outputs depth data into the color buffer.
Instead of using a compute shader to do the work, we set up a raster pipeline.
