Ver: 7.7.0 Playground: Babylon.js Playground Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes Desc: I’m building a scene that digs a hole when the button at the top right of the scene clicked, and when the wireframe mesh moved and the …

There’s unfortunately nothing that can be done (except maybe using another algorithm to compute CSG). CSG creates many faces very quickly, so after you’ve applied CSG a few times, your mesh can contain a lot of faces and it becomes exponentially slower to apply new CSG operations.

So, do it mean that the performance of csg can not be improved? What about the mergemeshes? Any ideas of making merged mesh work with csg?

I don’t know if the current CSG algorithm can be improved, it’s an external contribution I think, so it’s hard to know. But we already had this problem in the past with no good solution. I’m not sure what you mean by having merge meshes work with CSG… Merge meshes simply merge the vertex buffers of…

Even if it is just a single mesh, your poly count will go through the roof too quickly. You need to look into “destructible environments” and see what approaches fit your project/purpose. If you need e.g. dynamic caves, google for how “Red Faction 1” or “Deep Rock Galactic” did it. Or Minecraft.
