Severe overexposure when importing into Isaac Sim.

[nerakoo]

Has anyone tried converting a Blender scene to a USDC file and importing it into Isaac Sim? I followed the official workflow—the steps in the “ExportingToExternalFileFormats.md” guide—but the file appears unusually bright in Isaac Sim, and adjusting the lights doesn’t fix it. Also, has anyone used Isaac Sim to train a policy before?

Hi, I have a different issue. When I export using the given code:

python -m infinigen.tools.export --input_folder outputs/indoors/coarse13 --output_folder outputs/my_export13 -f usdc -r 1024 --omniverse

the export materials are not working at all. I am using IsaacSim 5.0.0. If I use the blender omniverse branch and export it muself to .usdc file then it seems to be working better but the texture quality (even after 4096 scaling as not good). What is a good export method?

Moreover, the blender omniverse branch is only available on windows and I don't want to convert between linux and windows each time so I would appreciate a good conversion method for this.

@nerakoo as for your problem, there is a code in the export script which spcififies the conversion of the light intensity between infinigen to usd for isaacsim. If you change the scale to something lower, it can fix your issue I think. Or you can use the blender omniverse branch on windows and there is a setting during export to usd where you can set the lighting scale too.
