I’m very interested in what you’re trying to do here. I’ve been wanting to make a retro [Zelda Inspired] RPG for Oculus Quest for a while now.
I just started toying around with vertex lighting from the ps1 style, the market asset is here
(Retro Graphics in Visual Effects - UE Marketplace)
I tore out all the low res effects since I really just want the lighting.
Just stumbled across this concept of Gourad Shading and now I’m wondering if that would be useful as well.
