Godot 4.0 : New features for godot game engine.

I used this game engine with the property scripting code GDScript and is easy to learn.
This is an procedual programming scripting language without OOP features.
The Godot game engine can be used with C# programming language.
Now, the author of this article name Juan Linietsky comes with news:
Yes, indeed. Godot 4.0 will also have a very cool Voxel based real-time GI.

Still, that is a different technique aimed at different use cases. Lightmaps offer significant advantages over any other technique when the following requirements are met:

  • Performance above anything else (for mobile, lightmaps are still a must-have)
  • Quality above anything else (no light leaking, ideal for architecture)
  • Lighting will not change (lights won't move)

If these requirements are met, then lightmapping is probably the best for you.

On this official youtube channel the author show us the result of these features.
You can download this engine from the official webpage.
