Delete Branch "makowalski/blender:usd-varying-uv-import-error"
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?
Change to map the USD "varying" interpolation type to Blender's
"Corner" domain type when importing mesh attributes. This fixes
value count mismatch errors when importing USD attributes with
varying interpolation.
Note that, for meshes, "varying" and "faceVarying" interpolation
are essentially the same in practice.
Looks good to me 👍
I was able to get blender to build today after some struggle (not my forte) but if this is indeed merged into main, the error persists, much the same as it did in my initial issue.
@benbrennanmusic Thanks for reporting this.
One complicating factor is that specifying "varying" interpolation for meshes is relatively rare and there are inconsistencies in how DCCs interpret this. (It's by far more common to specify "vertex" or "faceVarying" interpolation for meshes.)
I'm going to reopen this issue to investigate further. Would you mind providing a sample USD output from Unity where you are getting this error?
Done. added to the issue
Thank you, @benbrennanmusic.
