Useful Examples#
Here is a list of light path expressions examples you might find useful.
| Description | Expression |
|---|---|
| beauty | C.*L|O |
| direct diffuse | CDL |
| indirect diffuse without emission | CD.+L |
| direct + indirect diffuse without emission | CD.*L |
| full diffuse + illumination coming from emissive materials | CD.*L|O |
| full diffuse without subsurface | C<RD\>.*L|O |
| All diffuse path only (+SSS) | CD+L|O |
| specular reflection | C<RS\>.*L|O |
| glossy reflection | C<RG\>.*L|O |
| specular reflection + glossy reflection | C<RS\>|<RG\>.*L|O |
| specular transmission | C<TS\>.*L|O |
| glossy transmission | C<TG\>.*L|O |
| specular transmission + glossy transmission | C<TS\>|<TG\>.*L|O |
| subsurface | CW.*L|O |
| volume | CV.*L|O |
| direct emission | CO |
| indirect emission | C.+O |

| beauty per light (excluding emissive materials indirect contribution) | C.*<L.'my_light_label'> |
| unoccluded | C.*U |
clamped values in beauty (to subtract to the beauty C.*L|O to get the result beauty) |
C.*_ |
| full direct (equivalent of a rendering with diffuse depth 1) | C([^D]*DL)|([^D]*L|O) |
| full indirect (excluding all direct contribution) | C(.*DO)|(.*D.+L|O) |
