Greetings, 1. I loaded mesh to make UV's 2. Did UV's 3. I exported mesh to maya. 4. When importing back to Rizom, through Load UV's, i get black pieces, which: A: Could be repaired by making cut anywhere inside island, then weld that cut, then unfold. B: Could be repaired by repeating weld and cut C: Cannot be repaired inside Rizom whatever i try, only back in maya by quick apply planar mapping.
Point is, they behave as unfolded. In maya i can select that particular shell which have right shape under cursor from Rizom, but in UV spaces, they are invisible, located in 0U/0V. When zooming on selected shell (in case object is too small or too big), maya just position view in center, like nothing selected. In Rizom, they are not packable, unfoldable nor optimizable and when selecting black island and hit F (center selection) it centers exactly like maya, into 0U/0V.
Made a video of this issue, i performed B fix above drive.google.com/open?id=1XTLLfOCd-NW0a5883UX691Ai8Q5ir4_i
How to avoid to get those black pieces please?
Thank you

Hi jc,
this is a flipped normals problem. The black faces are kind of "invisible". You should flipp the mormals of that faces in you 3D app and all should be OK again.

Just figured out why C: above happens When welding object by selecting all edges, whole model turns black and cannot be used. But when selecting all islands, welding produce usable mesh. Video explanation 1. At start, I have exported and loaded UV mesh 2. U,O,P hotkeys 3. select edges and weld uv's together, then trying to use U, O, P hotkeys again. Unfolded island should appear 4. cut edges, then applying U,O,P hotkeys 5. undo several steps 6. Switch to F4 primitive mode island 7. Select all islands and weld 8. Cutting and U,O,P 9. Undo and repeate 3. Model turns black and unusable again. That means it's not random issue Video: drive.google.com/file/d/1rUHwVLpdMZ0fl6VylqL4Ag-5Mamr6ZzK/viewAlso script log: -- ERROR: vector<T> too long Same issue was reported here: forums.autodesk.com/t5/maya-modeling/error-unfold3d-error-vector-lt-t-gt-too-long/td-p/7864263

Maybe Remi or someone other can help here please?

Hi jc
Can you send me the OBJ file please ? remi.arquier@rizom-lab.com

Hi jc Can you send me the OBJ file please ? remi.arquier@rizom-lab.com Have you found any solution to this issue? I've encountered with this thing a few moments ago and lost couple hours of work

Hi John
Unfortunately not for now. I don't remember had the mesh for debugging this. I would need one (the simpler as possible).
