Ya that bites. I found out even more, meshes I made in Vue 3 that use Boolean imported to Vue 4 no longer work ;( that realy bits. I got a couple of gigs of work done here in Vue 3 format. I tried even different formats 3ds and cobs same thing works in 3 dies in 4. Only the objects that are in 4 work. Even the rocks work proper but imported stuff dies... That realy sucks if you just paid lotsa cash for a mesh now don't it? I got the patched version of Vue. I wonder if that was also in the original buggy 4.0. I'm running 4.02 right now.
