VoxelPlugin VS RealtimeMeshComponent

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.

Take a look at this: https://github.com/TriAxis-Games/RealtimeMeshComponent

Yeah, u can do everything in UE. This kind of things have a common name of procedural generation. U can use build in options, write it yourself or use a 3rd party component, one of the popular ones is https://runtimemesh.koderz.io/

I recently started learning ue5, and I wanted to make a random procedural terrain that creates itself on when the game starts. I almost finished it, and now I just need a faster way to create the terrain. I found the Realtime Mesh Component 5 from github, but there is also the same one with the same author on the marketplace for around 6$. What is the difference between the two of them? Thanks!

Personally, I generate voxel terrain with noise then mesh it using the realtime mesh component. This allows for fully 3d worlds with caves, overhangs etc and for runtime editable terrain.

You could use the Runtime Mesh Component to deform the geometry itself. The deformations are handled on the CPU, so CPU access is required on the mesh. And you can also offload the work to another thread, so minimize/avoid blocking.
