Karma

General

Only available in Houdini. Replaces Mantra.
Mainly used in conjunction with USD Solaris
Before a material can be assigned to geometry in Solaris its path must have been previously defined in the Scene Graph Tree before assignment.
There are three primary LOP nodes that can be used to apply shaders to geometry in Solaris.
- Material Library - Can create and assign shaders to objects.
- Assign Material - Only assigns shaders to objects but has more controls for overriding material assignments.
- Edit Material - Edits the existing materials from the imported USD scene.
Material Path is the path for scene graph not the path in Math Context (like the usual Houdini Way)
Using the dirt mask and rounded edge mask. karma

Nodes
