PTBT_ALBEDO: PathTracingBufferTextureId

Albedo (Path Tracing). Average albedo at the current sample count.

Type:

2

PTBT_DENOISED_RADIANCE: PathTracingBufferTextureId

Normal (Path Tracing). Stores the denoised radiance if denoising is turned on and complete for the current frame, otherwise, black.

Type:

1

PTBT_NORMAL: PathTracingBufferTextureId

Normal (Path Tracing). Average normal at the current sample count.

Type:

3

PTBT_RADIANCE: PathTracingBufferTextureId

Radiance (Path Tracing). The raw radiance.

Type:

0

PTBT_VARIANCE: PathTracingBufferTextureId

Variance (Path Tracing). Path tracing variance stored as standard derivation. Variance can be per channel variance or variance of luminance, albedo, and normal based on the path tracing configuration. Hooking up this buffer can increase additional cost.

Type:

4
