CoronaFabmtrl and multi/sub obj

Corona Corona for 3ds Max Help Required

Anyone know if its possible to render a mask with separate colours on a multi sub obj that has 2 CoronaFabMtrl’s ? Just seems to render it as solid and I think I have tried everything apart from splitting all the objects up which would be an issue in this huge scene.

Looks like a bug. This is now reported as (Report ID=CMAX-1992).
As a workaround, you can use the Corona Multimap with “Face Material ID” mode plugged into the CTexmap render element.
