How can I prevent my polywire for changing vertex numbers with deformations. It makes bad jittering on the uv. Any idea how to fix this? Point numbers are not changing.
It has to do with the Polywire calculating UVs downstream from the transforms on the input curve. You could apply your UVs in a different way, or in the case of the file I posted re-apply transforms to the UV'd geometry with a point wrangle
