Delete Branch "filedescriptor/blender:fix-gpv3-crash-convert-weight-group"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
A grease pencil test file
(can be found here: https://cloud.blender.org/p/gallery/5d9c6ee20f9018baaca071c3)
was crashing when converting to GPv3.
The index of a deform weight group was out of bounds.
We will have to investgate how this can happen, but
in the conversion code it seems best to ignore and skip over
invalid indices.
Thanks for the fix. A bit disconcerting that such weights appear at all, but since the rest of deform code seems to handle it well i think it's ok to ignore such weights.
