[1721416602]

Intro

Hi!

I am an engineer at EFORT Company, and I use MuJoCo for my research on exporting MJCF to USD.​​

My setup

MuJoCo:3.2.6
language:python
OS:ubuntu20.04

My question

​I want to convert a scene from RoboCasa to USD format for verification. I saved one of the scenes and exported it to USD using MuJoCo's USD exporter, but when imported into Isaac Sim, the scene keeps flickering.​​
