Baker's UV Boundary Filling and custom attributes Aug. 12, 2026, 3:37 p.m.
Hi,
This definitely sounds like a bug, though I'm struggling to recreate this case. Would you mind attaching a .hip file or providing some more information about your setup please?
Can you also please provide the version number of Houdini you're running into this problem on?
Here is my simple test case:

The only type of attribute which does not receive UV Boundary Filling is ID Layers/Int Attributes.
Many thanks!

Heightfield Convert sop creates uv.z breaks COP baking July 17, 2026, 5:30 p.m.
Hi there!
Yeah, this has been reported in other situations where some UV based SOPs output UV.z values.
There is a toggle on Rasterize Setup and Bake Geometry Textures for 'Remove UV Z Values', this toggle is ON by default in Houdini 22, but off by default in H21, as to not break backwards compatibility.
This should help with your bakes which have UV Z values.

Hope this helps!
