Why use cloth, appears broken surface

I unity3d in the construction of a sphere, and then use the Interactive cloth and cloth renderer, but appears broken sphere surface alt text

I do not know unity3d the cloth system, friends who wish to present a paper about it, thank you

Whoa, indeed, Radeon GPUs do not quite like one bug that we have in Cloth rendering. Thanks for the report, will be fixed in next release.
