Description insaner 2024-11-09 03:20:52 UTC

Patch at:

https://gitlab.archlinux.org/archlinux/packaging/packages/blender/-/blob/44a846df45bbc7437c464ac68290871523f2489c/blender-4.11-mantaflow-python-3.12.patch

was tested and works. Just modified the spec and recompiled the source rpm at 

https://koji.fedoraproject.org/koji/buildinfo?buildID=2575769

and installed the resulting rpm.

I'm using fedora 39, but I believe this affects more recent releases too.

===

Bug is that Python 3.12 seems to have introduced stricter checking for PyImport_AppendInittab() and when attempting to use fluids in blender, it immediately crashes with:

Fatal Python error: PyImport_AppendInittab: PyImport_AppendInittab() may not be called after Py_Initialize()
Python runtime state: initialized

Applying the patch above fixes the problem. Hope that helps






Reproducible: Always

Steps to Reproduce:
1. Run blender 4
2. Attempt to use fluids (eg: Object > Quick Effects > Quick Liquid)
3. Crash
