dravec_kyrobp_sidefxHi! Incredibly sorry for the late reply, It ended up being the USDs which the renderers read from not being properly set up due to some Solaris USD export options.
Happy New Year! Do you have a hip file you can share?
Hey, would you be able to be a little more specific? Started to play around with Karma and am running into a similar issue. Viewport renders are fine but the USD Render ROP is outputting black.
