You can get better AO results from the copernicus bake geometry textures.

ok.. this is crazy in my case textures do not update at all. just the first time you create them is like XPU refuses to create new rat files. But if you close houdini and open it again everything is fine.

I got it to work!!!
So I updated my nvidia driver to latest game driver rather than studio and everything seems to be working fine now.
Don`t know if this will help anyone else but here it is.

I just revisited this in Houdini 21 and the situation with Karma is slightly worse. XPU now locks textures too and no amount of updating textures or restarting renders does anything.

It's not a Solaris thing. RenderMan 27 works great: no file lock, change your texture, click restart and the render instantly updates to the latest version.

We did find a file lock bug relating to non-RAT textures on CPU on Windows, but otherwise unable to reproduce the problem in any other combinations.
Can you please file a bug, including your platform, texture format, and a reproducible case if you have one. Thanks.

Sorry I also went ahead and did a bug report.... I had a test file ready from my previous testing of UDIMs in Cops.
Here is a video showing the bug FYI.
