Please take a look at this.
This is the mesh submitted for the MARI Texture Challenge 2012. In MARI, my mesh is full of these funny little specks. You can’t paint on them, so first I thought they were small polygons, which had not been correctly UV mapped. But upon closer scrutiny, you can see that the shapes do not correspond with the tris underneath. They do seem to sit where one patch ends and another begins.
Any suggestions how to eliminate them?
