Your own pass for GBuffer for v7

[AndreyPrakhov]

Hi. Please tell me how to add my own pass to GBuffer for v7? Let's say some GBuffer.COLOR2 where the base color will be rendered into the texture

Hi,

the GeometryPass uses a GBufferConfig to manage its internal render target. This config can be modified via

postprocessing/src/passes/GeometryPass.ts

Line 114 in 32819bd

readonly gBufferConfig: GBufferConfig;

or by providing a custom gBufferConfig through the constructor options:

postprocessing/src/passes/GeometryPass.ts

Line 185 in 32819bd

gBufferConfig = new GBufferConfig()

Additionally, you'll have to modify three's built-in materials with custom shader code to render to the additional gBuffer textures. You can check ShaderChunkExtensions for reference.

Please not that this feature hasn't been tested extensively, so there might be bugs.
