Where can I get a .ms3d or some common file format of a hexagon that is tessellated say 256x256 triangles but the 256x256 fall with in 0-1 range so the hexagon is a fine mesh.

THanks!

I feel that you should bring an N-Gon into the viewer of your program and subdivide it. I really don't understand the 256x256 because a hexagon has 6 sides. Once you make your object, then any good 3D editing program should export it in the desired file format.

I'd suggest to build it up yourself with blender using the snap functionality. God only knows what the hell artists all over the world might put in the mesh. Such as screwed normals. Texcoords you don't need. Sharing vertices supposed to be unique...
