so I am working on Morphs for a customer and I need to keep the vertex order for important and exporting but both options are missing in Blender v3.1

@PrefoX as far as I can see:

  • The importer in v3.1 has not changed at all, the "keep vertex order" option is still there in a tab under "Geometry" foldout.
  • The exporter in v3.1 effectively always keeps the vertex order -- as if the option was always on. However, it does not keep the face order -- do you need that?

well everybody is missing the "keep vertex ordner" and the dev told me its always on but not there anymore. its fine if its always on but who would have known that its always on now. the option is still missing but a changelog would have been nice.

Yeah it definitely should have been mentioned in the release notes (and/or updated documentation), but it was not :/

If that option is always "on" and removing it from UI was intentional, we should indeed mention it in manual

That's what I'm trying to figure out (whether the option removal was intentional or not), stay tuned...

"Keep vertex order" is just always on in the new importer/exporter.

for Wavefront .obj (Built-In) Blender 3.6.5:
I would need an option for "Keep Face Order".
I made a Script that Exports and ReImports all Objects one after another but I need to save 2 Layers of Color Attributes instead of just one.
Looping through color_attributes.data and save all colors to List and apply them after ReImport does damage my Vertex Colors!

This issue has also 'broken" my addon UVlayout Bridge as the face-order is not kept. Not sure why this happens if that never was an option. How come in the old "keep vertex order" works, no talk of keep face order. But now it said "keep vertex" order is always on, yet now its suddenly the face order not being correct.

PS why was the status change from "Needs Developer to Reproduce" to "Archived" without any post?
