@marchcat Looks good - I tried it locally as well. Looks like there's just a trailing white space that's getting flagged in the pre-commit. Fix that up, and I'll merge it in.

@Geenz, thank you!
Actually, scaling to 1/100th helps with some models, but it makes things worse for others (mostly the ones I downloaded from Sketchfab).
I'll add another commit for dynamic scaling once I resolve the conflicts with your branch — rigging seems to have affected it somehow.

I mentioned this to Geenz already, but as this MAY (or may not) be related to the materials, I wonder if either of you are seeing GLTF mesh import messages that indicate "Error: Material of model is not a subset of reference model"?

Seen on all model uploads from Blender 4.4.3 GKTF/GLB built in exporter, even simple untextured cube using geenz/gltf-mesh-import as at approx. 6-May-2025. Maybe its fixed in recent work?

Meant to be quick feedback. Sorry for cluttering up the PR.

@aiaustin Please do not clutter up PRs with bug reports. File an issue instead.

"Error: Material of model is not a subset of reference model"

@aiaustin, you can click "Clear settings & reset form" to remove that error for now.
