Pretty interesting!

I've had experience on Unity, it was one of the first game engines I used to develop games on 3d animation vocational training degree classes.

That could be cool to make mods on it! Great work!

I've to give a review about the test, I see details, the map rendering is darker than the original Q3 ones. The head model doesn't appear in the HUD, also the attacker name and head model of the attacker, ... Well, I know that's still WIP and there are TODO stuff to be done.
Keep it, that's nice!

It would be cool to see people contributing this project.

Q3 shaders are different from Unity shaders, looks like it's using Shader Graph, right?

Since the Unity Fiasco back in September, I've switched to the Godot Engine, and the result has been most impressive, not only I'm getting more performance out of it, but also I get a lot less limitation that Unity impossed.
Right now the way shaders are implemented is that they are converted to Godot GLSL shaders:
Here is a video showing that in action on Godot 4:

Glad to know. That's better than I could expect, the future is shining here!

I would be pleased to contribute this project.
The project could start to bear fruit, so I think a port like that is worth it even if Godot continues to update its engine, even to make mods there.

I wonder if MD3/IQM model structures, like Quake 3 originally does, which are divided by head, torso and legs could work. That's also something I wish could be done.

......Like?
