Let's take a 3D model as an example. Is it possible to prove that it was made in broken 3ds max, and not in Blender?

Answer 1

It can and can be proved that it was made in blender, and not in 3ds max (although it is unlikely), but what was made in a broken 3ds max, and not in a purchased one, is not.

Answer 2

Make a simple project on two versions and compare the binaries.
