Remove unused Optimize Mesh import option from OBJ mesh import

[Calinou]

This option was enabled by default, but it did nothing regardless of whether it was enabled or not.

This kind of weird future-proofing like Godot 3.x's LOD parameters genuinely grinds my gears.

Would it not make sense to fix the option by calling generate_lods? I assume that was the intent behind this checkbox.

I expect that the fix would be to call generate_lods.

Edited:

The correct generate lod is from importer mesh and not the other one from surface tool.

The intent of this checkbox was likely to replicate 3.x functionality, where you could choose between several kinds of per-vertex data to compress (vertex, normal, tangent, UV, …). There was no LOD back then.

Edit: I've opened a PR to add that option specifically: #94108

I expect that the fix would be to call generate_lods.

That would be a different option which would be called generate_lods 🙂
