How about ImGui Unity?

I agree that immediate mode is a great paradigm. I wonder if you'd be better served using something like dear-imgui-unity -- dear-imgui is great and actively developed so you're more likely to see support for new features.

Hm, does this help: https://github.com/realgamessoftware/dear-imgui-unity?

It's made with Unity and custom shader, that will not ruin pixel art. Here's link to project github with rewritten shader. Original shader was written by truepak.

This shader was orginally described here by greatestbear. Then it was rewritten to match URP here. Now I have rewritten it to match URP 10.2 here. It's free.

Well, the best news is that I managed to find an implementation of Texel Space Shading. This shader allows the same lighting value to be used for the entire texel. It sounds strange, but it's easier to show it once than to explain it a hundred times (here is a visual comparison). This way you can preserve pixel art, but still use light, which means the walls won't be flat and the signs will glow. Another interesting thing I discovered in Unity is VFX. It would seem - nothing special, but this technology allows you to make sufficiently high-quality effects for pixel art, if you round off the particle size and location to the desired values ​​- in the end we will get the generated pixel effect (vfx is noticable at comparison video). That's all for now. At this stage, the project is open, the link to the repository at github.
