One mesh per file or Multiple meshes per file.

My current dilemma,

Usually I was doing only one mesh per fbx file.
Recently I started to shape ground from small patches and I decided to put all patches types in one file since it was easier to export all patches at the same time this way.

What is your workflow and why ?

For me, big standalone files get their own blender file. Characters, big buildings, etc. Which I imagine is standard stuff.

But if I’m working on stuff like… rocks, or trees, etc, then I usually have blender files to group them accordingly. I do this more and more as I get deeper into geometry nodes too.
