After making Rib-archive as Subdivision I'v got unpredictable changes in UV-coordinates. On polygonal model texture looks well. But on subdiv it's shifted and stretched.
Does anybody know it is Houdini problem or PRMan?

Hi renderfox, by shifted and stretched do you mean like this?

No, more dramaticaly!
And I meant not houdini's Subdivide SOP, but RenderMan's Subdivision.
I made subdivide RIB-archive by checking 'File as Subdivision' in Render tab in obj parameters and write out result to .rib archive file.
Resulting RIB rendered with not local UV shifting but total shift. I could attach results tommorow.

There might be some useful info on UV subdivison in Renderman here:

Excuse me to all for my stupideness:)
It was just "late evening" mistake. At morning I found problem in 30 seconds.
I had two pipes and one of that was not updated so geometry and attributes was from two different sources.
That's all folks:)
Thank you for cooperation
