Excellent information, thanks so much!
Now, my final question on the subject: is there any documentation on what LPE prefixes Karma supports? unoccluded is mentioned in the Karma Standard Render Vars documentation, and houdouts;shadow; was mentioned in a tutorial, but what about the others? I found a good explanation in the renderman documentation (https://rmanwiki.pixar.com/display/REN22/Using+LPE) but I'm not clear on which ones Karma supports.

A noob question: I saw an LPE holdouts;shadow;CDL in the tutorial "Houdini Karma | Render Matte-Phantom-Shadow", and there are similar-looking LPEs in this thread (post of Feb. 2, 2023 6:57 P.M.)
I understand CDL is an LPE, but what about this holdouts;shadow; prefix? I haven't found any documentation mentioning these names, and I'm not sure where to look---is this an aspect of Karma only, or... ?
Thanks in advance for your help.

Thanks! It didn't help. New .hiplc file attached.

I put a Background Plate node before my Karma Render Settings node, no holdouts. The background plate appears in the viewport but not in renders. A assume it's supposed to? Is there any way to make this work?

Thanks! Once I started looking around in the MaterialX library everything became clear.

MtlX Separate Vector 3 separates a vector into its components.
What's the accepted way of making a vector from its components?

Is the Signature parameter (e.g., in MtlX Multiply) documented anywhere? I was baffled by some of the choices. I did figure out what Vector3 (FA) meant.

PDG/TOPs » "Delete File Outputs From Disk" deletes more than output

I meant to say, I had made a couple of TOP nodes... restricting the output list to the copoutputs makes it behave exactly as I want.

Thanks so much! Everything is clear now. I made a couple of TOP networks to delete exactly the files I want. Kind of like we used to do in UNIX make files.

I have a tiny comp that reads a .png file via a File node and writes it out via a ROP File Output node. I have a TOP network consisting of a ROP Fetch node driven by the file output node. The comp renders just fine when I cook the TOP network.
However, when I do "Delete File Outputs From Disk" on the Fetch node, the input .png file gets deleted (as well as the node's output.)
I'm a noob, and I hope and trust that I'm doing something stupid. Does this situation sound familiar?
Thanks in advance.

Thanks! The updated driver allowed Houdini to get further and crash, but setting HOUDINI_OGL_SOFTWARE to 1 worked fine.

When I start Master and click “install non-commercial license” it becomes unresponsive and takes over 100% of the CPU. I've seen this complaint here before but haven't seen a solution posted yet.
FWIW, if I start the license administrator instead and try to save out the diagnostic info, it hangs in a similar way in the Save Diagnostic Information dialog.
Any advice is appreciated, even if it's “run away and don't look back”.
The machine is a gateway E-5200 with some manner of ATI video card. I just installed Win2K last month and got all of the Windows updates.
Thanks.
