how would you go about doing that ? also can it be done without having blender ?
You can compile bpy as a module I guess from what Agoose says,
This would also make things possible like passing a mesh to BPY, (a separate process)
And return mesh data via libloading, but I am not sure if it saves the mesh as a default ‘return’.blend or if you can snag a mesh from the running process,
