Almost a year later.... I've used this script a few times now, I've always gotten the same error message when trying to copy over weights
62 WeightsArray.push(NewWeights); "// ERROR : Object doesn't support this property or method - [line 62]" In the past the curves have always stuck fairly well to the geo so I assumed it was working properly. This latest time it seems to be ignoring the geo's weights and is applying a new envelope as if I'd just set a new envelope - lots of stretching between the curves. Has anybody else run into this? Does anybody know of a workaround for copying weights from a mesh to a curve?
