Texture Buffer Lights Node

Description

Texture buffers are 2D textures used to build a deferred image for various post-effects. To sample data from such a texture connect it to the Sample Texture node and specify UV coordinates and array element index for reading texels from the texture.

This 2D Texture Array contains lighting for opaque materials:

• Index 0 - direct diffuse lighting from light sources.
• Index 1 - direct specular lighting from light sources.
• Index 2 - indirect specular lighting (reflections from probes and sky).
• Index 3 - indirect diffuse lighting (diffuse lighting from probes, sky, and lightmaps).
