I've been working on a project getting a series of characters into udk and using dx11 features such as tessellation. Everything's been going ok, but im getting strange artefacting when i enter game mode or when i play my level. Its like the triangles of the tessellated mesh or something(see below).
It doesn't happen in the material previewer:
I've tried enable crack free, which does nothing, and i have tried having light baked and not. I'm not particularly sure whats happening. Without tessellation its perfectly fne too. I was wondering if anyone might know anything or give me a direction?
