Here is a simple demo to demonstrate my problem. Use a/z to zoom in/out and the cursor keys to scroll. The vertices are meant to have a texture set which blends into the surrounding vertices. I get this happening, but only on some triangles; others are drawn solidly with one texture. The wierd thing is that if you zoom in, you should see which tringles do what suddenly switch! No idea why the distance would make any difference, all 3 polys in each place have exact same vertices apart from alpha. AAAAARGGGH!
