multi GPU OPENGL ROP June 8, 2022, 5:35 p.m.

The Deadline parameters for setting GPU affinity only apply to Open CL jobs, and when rendering ROPs that expose a way to configure which GPU device to use (such as the Redshift ROP). The final GPU selection is exported to the $HOUDINI_OCL_DEVICENUMBER variable when the job is assigned to a machine. That parm won't have any affect on OpenGL jobs since the ROP itself doesn't have a way to configure which GPU to use.

Create intermediate directory & Overwrite existing .usd file June 7, 2022, 1:20 p.m.

Alright, the USD Render issue been fixed in the next daily build of H19.0. There's a new toggle (which defaults to on) that ensures that intermediate directories are created for the output image path.

ROP USD Output TOP node - does NOT overwrite an existing .usd file (after I "Dirty and Cook This Node")

This is because the file already exists on disk. PDG processor nodes typically have an option to enable caching of output files -- by default, if the file exists the work item cooks from cache on the next cook. If you Ctrl+MMB on a work item dot, you'll see the status is set to "Cooked from Cache" instead of "Cooked". The different cache mode options are documented here: https://www.sidefx.com/docs/houdini/nodes/top/ropfetch.html#pdg_cachemode [www.sidefx.com]

You can change the cache mode parameter to Write Files so that the node will always write outputs, and never cook from cache. Normally, Cache files are invalidated if the relevant parts of the scene are changed, if they're manually deleted on disk, or if an upstream dependency invalidates it cache files.

USD Render TOP node - does NOT create missing intermediate directories (after I "Dirty and Cook This Node")

This is likely just an oversight. We can expose that as an option on the node.
