Tried fresh installs of daily and production builds on a windows 10 box.
Houdini 20.0 renders fine. This error is thrown with Karma and Mantra ROPs in stage and out context.
Any help would be really appreciated.

Thanks so much.

I have tested the same scene in 20 and 20.5 rendering with Mantra and adding a cryptomatte object and material output.
The exr from 20.5 doesn't load the channel data in COPs or Nuke. The same scene rendered in 20.0 and below loads the cryptomatte data perfectly fine in Nuke and COPs. Is this a known issue? Is there a new option needed for 20.5 Mantra renders? Any info on this subject would be greatly appreciated.

Thanks so much tamte. That fixed it. This mirroring solution works for now.

Thanks for the info. I gave it a shot, and while the mirror pose SOP seemed to do the trick, for some reason it is breaking the skeleton animation when I put it back into the stream. The blue skeleton has the animation on the way into the rest of the network. I had used a stash pose higher up to store the original rest, and that works without issue. Not sure what breaks with this one. The white skeleton is the mirrored one I am storing, which is correct. But the main skeleton that comes out from the rig stash pose is the red one, which is the original rest_transform I extracted to mirror. I know that sounds a bit confusing, but maybe it makes sense.
Any more tips would be appreciated. Thanks

Loving the documentation for the retargeting tools. I am doing a full match setup between two skeletons that need a bit of rotation tweaks to get things oriented. Is there a way to mirror the tweak pose values from r <> l so I don't need to do each side manually?
It would need to properly invert some rotations, but not all rotations. Who doesn't love those little gotchas with rotations?
Any help would be greatly appreciated.
