I try to applied also the alternative way you tell but I don't see the UV, I continued to test.
- by triangulating I didnt mean Triangulate 2D node, just use regular Divide SOP at default settings
- do you see uvs on your mesh before Polyreduce? and are they vertex attribute?
- also you are talking about alembic are you feeding in packed alembic or unpacked geo and propery converted to Polygons? which is what you should do as most nodes will not modify geo of packed prims and many nodes don't work with polysoups
- your polyreduce is se to 100% so it will not reduce anything, nor anything to do with uvs, but also it would have kept them the same so the problem is most likely higher up
example file with some kind of source alembic may be better than screenshots
ok, now I understand and found a way, now works.
