godot_voxel VS VoxelPlugin

Don't do this, CSG is unoptimized. Use this.

Take a look at https://github.com/Zylann/godot_voxel, which would be a great starting point that you could build game mechanics on top of.

Currently all our major C++ based number crunching is in the GDAL. We haven't had to make in-house GDExtensions or Modules, yet. But we do also use Godot Voxel. Both are good examples of where you'd want more native speed.

I originally ported Qodot to an engine module that required people to compile their own engine (like godot-voxel) but users were turned away at this first roadblock.

I really wanted to use it but sadly it might be hard to export projects done with it cuz it's not a gdextension yet https://github.com/Zylann/godot_voxel/issues/333 still possible but i think you gotta compile something.

If you aren't adverse to doing a custom editor build you could add https://github.com/Zylann/godot_voxel

To give some practical examples. At my day job we use GDAL (a C++ geospatial data processing library) and Zylann's Godot Voxel (a C++ engine Module) https://github.com/Zylann/godot_voxel

The master branch of this one will also build as a GDExtension for Windows. This one is successfully building regularly, but structured different than the rest of the GDExtensions I've seen. I haven't played with this project too much yet, but it's an insanely powerful module/extension: https://github.com/Zylann/godot_voxel

There's also a performance question. While we can now use Blueprint nativization to convert Blueprints to C++ the result will be a fairly naive version, fast enough for most purposes but not if you're trying to push every bit of performance. This is where you're looking at making sure you're hitting things such as using the CPU cache as well as possible for an ECS system (Look at ENTT or Flecs if you want to see what they're about and why you'd want one), or a system needing to process massive amounts of data quickly such as the Voxel Plugin.

There are some existing plugins, such as the voxel plugin that you can use, though keep in mind features like multiplayer are behind a paywall.

Is unreal/unity efficient? No. There is large amounts of overhead, as they were designed for other types of games. Voxels have many unique optimisations that won't be available. You'll need to do a lot of "patch-work" to the engine. This patch-work may make this overhead extremely small, and there are some very powerful projects on these engines that are efficient (e.g., Voxel Plugin). Having to ignore a lot of the a game engines features, such as physics, is a key reason people decide to just go through the extra effort of making their own game engine.

Thank you! I am using the Voxel Plugin for Unreal to generate my planets, there is a free version you can play around with: https://voxelplugin.com/

I used Voxel plugin

Anyway here it is https://voxelplugin.com/ you can research all about it.

No one has yet mentioned VoxelPlugin for Unreal which you could use alongside a Lua Unreal plugin.

Try https://voxelplugin.com/

I'd look at Voxel Plugin. It supports runtime edits.

Hmmm I don't have a lot of experience with that but I used the Voxel plugin once to make a planet map and it was pretty good. There's even a free version if you don't want to invest. Most other plugins cost hundreds so that's good. It has a ton of features, check it out.
