Hi Tonyote,
have you also Textures inside your Slot and have no problems?
To Tom:
I have to detach every ID Face to use the Multimaterial, aaarrrggh

You can imagine the extra work when there are 30-40 IDs to detach
every time. My fun from RC5 till MXW 1.0 is little gone.
The new features are really enhancing but the workflow what NL advertised is till now not implemented.
Would be very nice to eliminate this for the next Plugin update
(hope soon). I thought NL will take care for this problem after RC5, where it has began.
Schorry vor mei bat enklisch.
