3.7.3.3 how many non-zero weights per vertex

tksuoran opened this issue · 1 comments

Joints MUST NOT contain more than one non-zero weight for a given vertex.

What does that mean, exactly?

The line was rephrased in a larger set of clarifications by #1997. The intended meaning is closer to:

"A vertex MUST NOT contain more than one non-zero weight for the same joint."

Probably this wording could be improved further.
