Avoid TriangleFan in built-in mesh node
Avoid TriangleFan in built-in mesh node
TriangleFan are present in D3D9 but have been removed from D3D10 and D3D11. My suggestion, avoid using them. The reason they are no good anymore is because they do an awful job as far as attributes interpolation are concerned (such as texcoord or normals), because you can do very thin and elongated triangles with them.
