I´ve done it a thousand times in c4d: selecting some polys of an object, setting a selection (polyselection tag is created) and then applying a material only to that selection. With maxwell (plugin) it wont work! Well it works 1 time out of 20 - and I cannot reproduce the failure properly. Seems like random...
I read an old post from 2007 "Selection Sets" but that did not help me.
Checking the scene in studio I clearly see that one time selection sets get exported and the other time it wont
Any helpful thoughts on that?
P.S. drag and drop on selections only work with c4d proprietary materials - I did selection setting an naming by hand (double checking)
