Unreal Mannequin

I created some custom skins and animations for the Unreal Mannequin character. I want to share the skins and animations with other people by allowing them to download them.

Is it against the rules to include the actual mesh and skeleton, which I did not create, as part of the free download?

If you mean a general public distribution, then no you can’t distribute the mannequin asset. If you mean a distribution on Epic’s UnrealEngine GitHub network, then it’s fine.
