Morph3D - MCS 1.6 and Artist Tools Free have released Morph Character System (MCS) and Artist Tools free for a limited time.

The MCS 1.6 lets you create characters for use in Unity Game Engine. You can also change clothing, hair, accessories and weapons  which will adapt to your character, should their shape change at anytime.

Morph3d have a fantastic team of artists creating content (many who also publish at which is great, but now, with the ArtistTool's being released, there's nothing stopping anyone from creating their own niche content for unity games that use MCS

Unity is a game Engine (like UE4) There is nothing to stop it being used artistically but for anyone reading that is just interested in getting started with 3d art should try DAZ STUDIO and Blender 3d
