@regal solstice sorry to bother you, but i was wondering if there were any update on this MDL node from this post?https://forums.developer.nvidia.com/t/houdini-mdl-shader/172755/5

and i was trying to install this HDA to houdini 21.0, seems it's not working
also, according to the readme file, i should copy the husdshadertranslators folder into the local Houdini python extensions directory. but i did not find any python2.7libs folder under houdini21.0 folder.

and also, is it hard to write mdl material in houdini using python myslef? is there anything i could referenc to?

Houdini MDL shader

Hey @Jiucao , Here is a node that allows you to assign MDL materials in Houdini. Note that Houdini does not currently support previewing MDL materials, but the MDL assignments exported from Houdini are viewable in any application that supports MDL. MDL_Node.zip (12.4 KB)

good question! I haven’t been at NVIDIA for a while now, but maybe @compact axle knows?

without knowing anything about the current system, I would make some guesses:

  1. Houdini moved to Python 3. if that’s the case you can ask ChatGPT Codex / Claude to try and solve this puzzle for you and get the HDA working.
  2. You can embed an MDL directly through python into USD! it’s just an Sdf node that gets added. Once again, AI agents are your friends here
