Hi there !
I've got recent crash since i've upgrade recently forest & vray at the same time.
Looks like we've got some troubles with materials.
vray : 3.10.02
forest pro : 4.3.4
max2015 sp3 / ext2
Don't know exactly where the crash come from, because all softs and plugs have been updated during December (max, vray, forest and more)
I join a vrayLog.
Off course, scene has been created before update, and was fine.
If anybody has an idea, i'll take it, i'm still searching.
After some trys, i can manually fix this problem by reloading each geometry one by one, but on multiple bigs scene, this is really uncomfortable.
