Keep meshes separate (don't combine layers)?

[bigrig2212]

Hi there - wondering if there's an option to keep layers as is in the mesh, versus combining them all into a single layer.

i was trying:
gltf-transform optimize "$file" "output/$filename" --join false --simplify 0.0

and
gltf-transform optimize "$file" "output/$filename" --simplify 0

But those didn't work. Suppose im just not finding the right option?

Eg: Maintain this structure

Versus combine it into this:

The --join false --flatten false options were added in v3.1, by #838, so you may need to update to the latest version. Then this would work:

gltf-transform optimize in.glb out.glb --join false --flatten false --simplify 0.0

Or --no-flatten --no-join should have the same effect.

Wonderful! Works like a charm.
