I use TraceGeometry within a ChannelShader. I want to figure out which polygon gets shaded at the moment. I thought that I could figure this out with using the VolumeDatas TraceGeometry method. But I always get the ID 1 returned, no matter which side (of a cube for example) gets shaded.
Does TraceGeometry work correctly? Is the "Face ID" really the polygon ID?
Maybe there is a better way of determining which polygon is currently shaded?
