3DSMax Multi/Sub-Object material / CoronaRaySwitch bug

If you plug a Multi/Sub-Object material into CoronaRaySwitchs material slots you get a render error (see attachment)

and guess what it says :wink:

right you are maru, that’s a huge shame. about 90% of our sets use multimats. and all our skinned characters.

Well, do you need rayswitch for them?
