@cgstrive In order to pack those islands you should adjust topology options.
BTW: RELEASE 1.8 is ready:
‘Process Self-Intersecting UV Faces’ option was improved. Now with this option enabled add-on can also process islands with 0 area. It basically means that now add-on can process islands with any topology. In other words: ‘Process Self-Intersecting UV Faces’ guarantees that ‘Invalid Topology’ error will never happen. Encountering a topology error with this option enabled is now considered a bug which should be reported to us The good news is that this improvement is available in both packer versions: extended and professional.
We added a new operator: Validate UVs. This operator performs the detailed validation of currently selected UV faces. In result it selects all faces from the set which are considered invalid. Invalid faces are:
- faces which are self-intersecting
- faces with area close to 0
- faces overlapping other faces.
As any functionality from UVPackmaster the validation procedure is very efficient - it’s all thanks to our sophisticated algorithms Note that validation operator is available in the pro version only.
What else? The corner case with square islands packing was fixed (no chessboard anymore, though it wasn’t very problematic issue as default Blender packer is good enough in square packing ) Beyond that we included a few minor improvements.
And the best of all: despite adding new features and improvements the price of the add-on stays the same for now.
