I was testing the dx11 tessellation, and it worked with skeletalmeshes using the MTM_Flattessellation, but when switching to MTM_PNtriangles in a material assigned to skeletalmeshes, UDK crashes.
I can use PNtriangles with staticmeshes, but not with skeletalmeshes.
I have tried some things, like a very simple material with only a difuse and a vector2D for the TessellationMultiplier slot, marking the “use with skeletalmeshes” option, and the same result. With some different skeletalmeshes. Crash with all.
I did the test in UE4 time ago and works very well, but in UDK never worked. It’s only for staticmeshes?
