Hi,
Sorry for my long response time. Here is a demo Project. It is a vs2010 sollution in debug build mode.
demo
If you press f1 the terrain is morphed randomly, if you press f3 the mdl is morphed.
On f2 you can call fixnormals for the terrain, on f4 you can call fixnormals for the mdl.
Thank you for taking the time to look onto this.
