Snapshot layers
The Iray engine is available for image, video, VR object and VR panorama snapshots. In the corresponding Snapshot editor, select Iray as the render engine.
When the snapshot will be saved in a format that supports layers (PSD or PSB), Iray can split the image into different layers.
Render direct and indirect contribution separately: renders separate layers for the direct illumination (light sources) and indirect illumination (global illumination).
Available layers:
Diffuse layer
Specular layer
Glossy layer
Emission layer
Alpha layer
Depth layer
Normal layer
The calculation of layers does not include transmission.
