Hi I am having an issue while trying to render an scene made with quite a few USD assets with karma in xpu mode. I am trying to rendre through mplay and directly to disc as well, but it is just stuck during initialization. Some times in mplay it renders only 0.6% and then stoped and then it keeps initializing. That doesn't happen with CPU , it renders correctly while using cpu. The problem appears only with XPU. My pc specs are :
AMD Ryzen 7 5700X 8x 3.4GHz (max 4.6GHz) , GPU Nvidia GeForce RTX 4070 Super, and 64 GB ram.

Please some help!

Hi, I am trying to batch convert mantra materials of kitbash models to materialx , I am using houdini 20.0 but the tool casts this error:

I wonder if this functionality works only for houdini 19?
or if I am doing something wrong
Thank you in advance!
