I need to make a custom operator in C++ which needs to do interpolations between multiple inputs and outputs similar to how the envelope weight operator interpolates weighting points to deformers. I only need the envelope weights property (as seen in the envelopes weights point cluster), not the envelope weights operator as my custom operator would take its place in the relationship.
Looking through the SDK documentation I cannot find the preset to create just the envelope weights property. The workaround of creating an envelope and freezing it doesn't work either as the envelope weights property disappears along with the envelope operator. Although I can create an envelope and duplicate the envelope weights property, then freeze the envelope, that's a bit too hacky for my needs. If I do somehow create that envelope weights property, is there any special way I need to interface with it inside of my custom operator? Thanks, Matt
