I have my mesh with 2 layers. One is main sculpt, the other is detail. The mesh in question has 2 Uv maps.
I produce my Displacment maps, then went sculpted the higher detail on the other layer.
Finnaly I turned off sculpting layer, went down to Sub D lev 1 switch morph target and hit grpsplit, instant crash. A few times it didnt, but most times it does. When it down crash iv lost all by restored morph targets.
Its a shame I cant just hide a part to produce Normal maps.

Havent a clue why it ended up here, I was in question section?
