Light Filters - Arnold for Houdini
Note:
The default spot_light type (disk) does not currently work with the gobo light filter. A workaround is to change the type to sphere or point when using a gobo.
- In a Material Library LOP, create an Arnold Material Builder
- In the Arnold Material Builder, create a Light Output.
- Connect a light filter (such as light_decay or gobo) to a light_filter port on OUT_light.
- In the light parameters, under Arnold > Shaders, select the ArnoldNodeGraph (the Arnold Material Builder node).
