Hello,
I’m trying to calculate the stretch of a surface by comparing the uv and the geometry.
For mesh, it’s easy, there’s the Face Area node, but I can’t find it for UV.
Is it possible to obtain the UV surface ?
Hello there!
Well, you could perform Set Position on the geo with Position input taking UV coordinates. Then use Sample Index to read relevant Face Area data.
On the other hand… for this you’d have to find away to properly split the surface at seams first. Split Edges might be all that’s needed for it and it shouldn’t change face indices, but I’m not entirely sure…
