I'm trying to figure out how to get the transform matrix of a light filter.
I found I could get the matrix of the light that the filter is attached to with AiNodeGetMatrix(sg->light_filter->Lp, "matrix"). I am planning to do local overrides to Liu independent of the light transform tough so I'm wondering how to pass the transformation of the light filter itself into the shader? I found in Maya I cannot transform the blocker in the viewport at all and in Katana the transforms of the blocker won't get passed onto the .ass file.
Surely there's something I'm missing :)
Any help would be appreciated!
