Performs a fuzzy inference operation over each input to determine the truth of the fuzzy set defined on this node. Represents an input or an output (or both) of the parent VOP subnet. Takes an angle and an axis and constructs the quaternion representing the rotation about that axis. The current workflow evolved from this previous system, and needed to work with mantra, rather than the shading system and the renderer being completely written from scratch.

Computes the intersection of a ray with geometry. Displaces the surface along the surface normal by an amount equal to This geometry can be used for display in an OpenGL viewer. That mixable representation still needs to go through a Compute Lighting stage (represented by the Output node) to become the final result used for shading. The gallery of materials in the direction D, a. Computes a local transform for a KineFX point using its and its parents world transforms. By default they have expressions that use the prim name, which is itself based on the name of the Component Ouput node.

Returns arrays of point transforms given an array of point IDs. values, adding noise, filtering, and color correction. Go to the /shop level It simply uses the file paths of the output files to add an entry to the layout database. If not, you might want to duplicate the Component Output node and change its file output parameters to write to a more centralized location (like a shared asset directory), write the files there, and then add those files to the asset gallery. Override a materials settings per-object or per-primitive. For example, the Principled Shader Core contains the basic functionality of the Principled Shader, leaving out convenience functionality (such as pre-built texture UI).
