hi i have a mesh made in sketchup - I bring it into unity as a .fbx and unity seems to create a bunch of sparklies over the mesh when i generate a lightmap. I have tried imnporting the mesh to 3dsMax and welding the verts (that has no visible effect apart from increasing the number of verts!!!) I have tried splitting the mesh up differently too in 3dsmax, I have also tried getting rid of mip maps from the textures.
Any ideas???
