Selecting this option will split those odd polys away from the rest of the mesh and move them back into the Edit space, which then allows you to reflatten them to fix the problem. Undrop Odd Polys Odd polys are ones that have collapsed UV coords this is where two or more UV coordinates are welded together (imagine a quad in 3D space looking like a triangle in UV space). This option could break point correspondences between morph targets as the geometry is being modified.ĭetach Flipped UVs Tick this option if you want flipped polys in UV space to be detached into separate shells. A summary of the changes made will be displayed once the file has been loaded. The clean will also remove duplicate faces. an edge is shared by more than two faces) then ticking this option will fix the problem geometry as its loaded. Weld UVs If the loaded mesh has seams (green edges) between adjacent polys, reload with this option ticked it'll weld all co-incident UVs together.Ĭlean If the loaded mesh has non-manifold edges (i.e. Otherwise, select New to delete any existing UVs and start with a clean slate. If the mesh isn't a subdivision surface, then select Poly.Įdit / New If your mesh already has UVs and you want to reflatten them to reduce distortion, select Edit. The subdivided surface will then be used in the flattening calculations, rather than the control cage itself, producing more accurate results.
SUBD / Poly If the mesh being loaded is the control cage for a subdivision surface, then make sure that SUBD is selected.
