MDL shaders support in Karma June 26, 2025, 6:50 p.m.
I came across the same issue recently with Evermotion MDLs.
Here's a quick script that converts them to USDs:

Note that it probably won't work on anything other than the Evermotion materials as it's hardcoded to look for that formatting.

Hey there, I have exactly the same problem. I need a AOV where my unlit mat particles with a translucency of 1 show up. How would I e.g. get a velocity AOV?
Thanks!
Unfortunately I don't think you can get a velocity AOV from unlit particles.
As far as I know your best bet would be to render a separate pass with the transmission set to 0 and opacity at 1. Then you can add an AOV to output the velocities primvar.

Use an LPETag LOP to add a tag to the various prims you want included in the AOV.
Then add an LPE AOV with the source name set to
