I see Manufactura 4K has released something, the guy does work. Used a lot of his assets with and very impressed he’s very easy going / helpful.
I don’t mind buying art assets or materials as long as I have express permission to modify them in any way I choose. Characters are a little harder, base meshes are useful and char packs are great for prototyping…
UI packs / inventory systems etc. are always useful. Oh and Skybox’s are always great to have!.
