Thanks for the detailed reply and for mentioning you prefer “just models” without built-in logic / Blueprints – that’s exactly how I like to structure my packs: clean modular meshes, a few example prefabs, no forced gameplay systems so they’re easy to plug into your own logic.
I’m more of an environment / level artist than an “everything” generalist, so I aim for complete environment sets (architecture, interiors, props, foliage, a consistent style language). I’d rather push quality in one area than spread it thin across weapons or characters.
I’m also seriously thinking about going deeper into Unreal – next year I want to build a tool for migrating whole Unity projects to Unreal without having to redo everything by hand. If that works out, I’m planning to drop several big packs on that engine as well.
