Fix build.

Thanks for the PR! What was the crash you were seeing?

https://github.com/mikedh/trimesh/blob/9dbb10cf76c5fea6ed217b0d18e9c64b6cb16a2e/trimesh/interfaces/generic.py#L45

So this should be evaluated in the template to: mesh_pre = ["file_name_a", "file_name_b"]

Where wouldn't this change emit: mesh_pre = '["file_name_a", "file_name_b"]'

Which then the loop would be through characters of the string, rather than file names?

Hi,

I've checked the history of updates which Guix index has, it looks like it was valid on 3.10.7, which I can't reproduce it after upgrade to the 4.5.2. It might be "self healed" between versions :-)

The link to a commit where the package was added https://git.savannah.gnu.org/cgit/guix.git/commit/?id=b4b93035c1c4dda16b8399fc77b6ef150831ef1d

Thanks, Oleg

I tried this in a branch and it fails test_boolean for the reasons above. I think the guix package can probably update to the latest trimesh, and remove that patch. I recently added blender back to the docker tests so if you pull in main to this PR it should also be caught in CI:

Thanks for the followup from GUIX!
