Hi,
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!
Thanks
