Hi. I was the guy brought this issue up back in the discord Omniverse server.

I haven’t solved this, I just want to also reply here to get more attentions from the software team.

Btw, we actually have the exact same GPU and driver version. Could this be the problem? I will install a newer driver later.

But still, I hope software team people can look at this weird bug.

Could you share the discussion link in Discord?

Could you try using Isaac Sim 4.5.0?

[HaoyuMa]

In 4.5.0, this bug also exists for me.

4.2 is broken for me. 4.5 takes a lot longer to load as it gets stuck on this file for like 3 mins, but then I can use it after:

Updated to the 570 driver and 4.2 is still broken.

Hi @VickNV , here is the link: Discord

4.5 at least loads for me, but it has a lot less material kinds, so even if that works, feels like a downgrade.

[HaoyuMa]

Does material creation work for you in isaac sim 4.5.0 after you upgrade the driver?
I also upgraded to 570 driver but the material stil can be loaded for me.

Did you do anything else?

[HaoyuMa]

I think there are extensions that will provide with you more material kind

[Istvan_Fodor]

Hi @HaoyuMa , I didn’t do anything else, just updated the driver, but I am not even sure that was the solution.

It was kinda weird, because on one start I was able to create materials in 4.2 and 4.5, even before the driver update. During that run I installed the new driver. Once I restarted my computer I could not create materials in 4.2 again, but 4.5 works.

[HaoyuMa]

Hmm. Thank you for replying to me.

I guess I will wait for the software team to fix this. This is a really weird problem and to my knwoledge, there were previous forums also brought this problem up. And some people may be able to fix it by reinstalling.

I guess I am being unlucky that none of solutions work for me.

[Istvan_Fodor]

My workaround before 4.5 was that I just used USD Composer (2023.2.5) for material / scene editing, because loading materials that were part of my USD files still work fine for me. Maybe see if you can use that in the meanwhile?

[HaoyuMa]

Hi. This is the follow up regarding the material loading leading to crash. I have found out the solution. All you need to do is to clean cache from the app selector and --user-reset. This icon problem I believe is related to the extsCache. And problem arises may be because I run ./post_install.sh and change\rename the installation folder later. Hope the software team can fix this bug in the future release.

I presume this relates to the issue you encountered in Isaac Sim 4.5.0. Please create a new topic specifically for the 4.5.0 issue, and provide detailed steps to reproduce it. Thanks.
