System Information
Operating system: Linux
Graphics card: NVIDIA RTX 3050

Blender Version
Broken:
Blender 4.1.0 Alpha
build date: 2023-10-07
build time: 22:23:53
build commit date: 2023-10-07
build commit time: 15:12
build hash: 8c1c782853
build platform: Linux
build type: Release

Worked: (I'll test it with earlier commits and update this part)

Short description of error
Blender crashes once I open this project. It's in the attachments.

This is in the logs:

../src/intel/isl/isl.c:2235: FINISHME: ../src/intel/isl/isl.c:isl_surf_supports_ccs: CCS for 3D textures is disabled, but a workaround is available.
Read blend: "/home/omar/blender_projects/test1/crashing.blend"
terminate called after throwing an instance of 'pxrInternal_v0_23__pxrReserved__::UsdExpiredPrimAccessError'
what(): Used null prim
Aborted (core dumped)

Exact steps for others to reproduce the error
Just open the project in the attachments. It'll crash immediately.

Edit: More accurate steps in this comment: #113400 (comment)

I'll continue debugging and see why this is happening.

Does not crash in 4.1 5c98d53125, not 4.0 66c05fe368, will check earlier.

I pulled that exact version (5c98d53125) and it's crashing. Here's the entire system info file

@ChengduLittleA
If it didn't crash on your machine, did it show any warnings or errors about the content of the file? Maybe that'll tell us something.

It does show

Runtime Error (secondary thread): in Open at line 873 of /src/build_linux/deps/build/usd/src/external_usd/pxr/usd/usd/stage.cpp -- Failed to open layer @/home/cuda_test/monkey.usdc@

in the terminal, and from the crash log, pxrInternal_v0_23__pxrReserved__ could be related to USD, but here it's not crashing. It could be related to that /home/cuda_test/monkey.usdc file, since it's not present on my machine, it may not trigger the crash.

Oh I didn't know it still remembers which USD file it was imported from. Interesting ...

Actually when I deleted (or renamed) that file, it's no longer crashing. So it's probably expecting this file to contain something but it has been overwritten (contains a whole different scene).

I found a more consistent way to reproduce it:

  1. Create a blender project where the Camera has keyframes. Let's call it Project A
  2. Export Project A as USD. Make sure to export the animations too.
  3. Create a new empty project and import that USD file to it. Let's call it Project B.
  4. Create a third blender project. Rename all the objects to something else so that there are no common names with Project A. Let's call it Project C.
  5. Export Project C to the same USD file.
  6. Open Project B (Now it's linked to the USD file and expecting to see the objects from Project A but they're actually from Project C).
  7. Crash ..

I have attached all these projects and the exported USD file

Can confirm with your step :D it's not necessary to save project A and C, just B is enough.

  • Default file
  • Insert key frame on camera
  • Export to USD (with animation)
  • New default file, delete everything
  • Import that USD
  • Save as blend
  • New default file, rename everything so there's no objects that had the same name as the original default file
  • Export and overwrite the USD
  • Open the blend file you saved

Crashed in CacheReader_open_usd_object. Seems to be a internal problem with USD.

I see that a simple try and catch around usd_reader = archive->create_reader(prim); would just avoid the crash. And in an exception we just return a nullptr.

But in general, I don't like the idea of referencing an external file. I mean if we need that file to be in that format, why not just have an internal copy inside the blender project file? Because it's very likely that users and 3rd party applications would treat the USD files as temporary disposable files that could be deleted or overwritten after they serve their purpose.

I'm not quite sure about why it needs to reference a external file, it may has some other design concerns like project sync (which I doubt). I think the best thing we could do find out what exactly is triggering the problem than to simply have a catch-all.

After some digging, now looks like that this reference is essentially caused by the Transform Cache which will use the USD as the transformation sequence as the source file to load animation, so this is where the reference comes from. It still should not crash it.

@makowalski maybe you could check?
