Short description of error
When I use smart UV project on my mesh it hangs and then never finishes.
Exact steps for others to reproduce the error
I created a mesh from a pointcloud in MeshLab. Then imported it as an OBJ to get uvmapped. I decimated to about 1 million polys. I ran a sample mesh through smart UV project at 0.3 island margin and it worked in about 35 minutes. But another similar mesh (the real one) also around a 1 million poly count just hung for 12 hours and nothing ever happened. Is there more information on the smart UV project tool that handles meshes differently? I understand it isn't a one solve all button and it's hard for you guys to troubleshoot without a sample mesh (it's really large). But some insight on this might help me make better decisions on what I can do differently. Thank you!

Changed status from 'Needs Triage' to: 'Archived'
This is a Python script which wont perform well on high poly meshes.
Made a TODO for this task #76532 (Improve performance of "Smart UV Project").
This is now ported to C and should perform better, although it may still be slow with millions of polygons.
