I wonder which engine is the only one you're allowed to use it in.

game assets tend to be highly engine-specific things by their very nature.

it can be possible to start from some raw assets when moving to another engine, but even then you may have, say, a character rig setup that's great in one engine but a huge pain in the ass in another.
