I was in the process of creating my own "retro" system with 5.3 but if I can save time and have a tested solution, I'm definitely taking a little shortcut :)
Just for clarity's sake: this is not intended to be used as "game engine" right? It's most for displaying single meshes (so, not a world) if I got it right.
How does this compare to your PSX engine?
I wouldn't mind a middle-ground solution able to merge retro aesthetics with modern features (volumetric shadows, GI via lumen).
Have you considered implementing per-texel lighting and multiple light support?

You're right. This plugin is designed to render a few meshes and not a game world. Although, you probably could render a small scene too.
Visually it's pretty much the same as PSXFX except for a few differences like an improved depth error effect due to a lack of depth buffer and custom sort priority.
It already supports multiple per-vertex directional lights. I might add point lights in the future.
I see, thanks for your reply. I was probably asking for something out of scope for a PSX-like engine - per-texel lighting is far from common!

I'd have another question but I'm going to make it on the correct page (the PS1 engine: are the material graphs available for us to be customized? I'm assuming you're using a master material?).
When I watched the demo I couldn't but notice the Red Cross usage: maybe not you, but someone using that model could get into a few issues - I speak for personal experience :P
Geneva Conventions
It's an easy oversight but the red cross is veeery easy to trigger (Even Quake had to replace that symbol).
