Hi Steve, I am seeing something with materials in the beta V6.
I made a solid box( as a test) , then went to materials. Chose custom material Wood. I chose pine of different verities on this box. As son as I applied them the program asks to be closed. I repeated it. I sent it into tech. Thought maybe you would like to see if you get the same result. —Mark
I’ll let tech take a look at this first.
