Hello
I currently use Vray for 3ds max as rendering platform for my USD stage from Houdini. And I found a few issues. I created USD stage in Houdini 20.5 and latest Vray 7 for Houdini. In 3ds max 2025 I use USD 0.9.0
- LightMix is not working with USD lights, so I cna’t receive separate light channels
-Vray Camera setting not read from USD stage, in Houdini I created Vray Camera, and made setting with DoF and so on, but in 3ds max this setting are not readed
-VraySampleInfo for getting UV’s render elements is empty, so it’s not read UV’s, but mapping on render is anyway correct
Most likely not supported. It doesn’t seem to work in Maya, either. I made an improvement request for its implementation (internal tracker ID: VMAX-14969).
This is already logged (internal tracker ID: VMAX-14372). I’ll add your report to it.
This works for Maya, and strangely, in 3ds Max, it works for Light nodes, but not geometry. Logged as (internal tracker ID: VMAX-14968 ).
I’m also found that LightLinker not working, so in Houdini for some light I exlcuded some objects form illumination, but in 3ds max is ognored. not sure f it USD in 3ds max related or Vray
This is noted in the documentation page (the very last row of the Temporary Limitations paragraph).
