Multimesh collisions

Dschoonmaker

I'm using a multimesh to make a large terrain(I know it sounds strange), and need to generate a staticbody for it. The mesh is a cube. I could create a staticbody for every block, but that would be a lot of staticbodies. Maybe there's a better way to generate a single collisionshape using every instance in the multimesh? Has anyone done this before? Thanks in advance.

Can't you model your terrain in like, Blender, then import it as a mesh, and generate the collision shape?

I've done some experiments with this: https://www.reddit.com/r/godot/comments/elwxg9/a_simple_comparison_between_zylanns_terrain/

Also, are you aware of Zyllan's plugin and module? Are you trying voxels? if so, the voxel module may do it: https://github.com/Zylann/godot_heightmap_plugin https://github.com/Zylann/godot_voxel

Oh, yeah I've seen your comparison actually. One of many reasons I don't use zylann's heightmap plugin :).

For my game, I would make the mesh in blender and use a terrain shader, but this game is procedurally generated and can't be modeled. I actually found that multimesh is slower than arraymesh, at least for collisions(I think for rendering too - though that doesn't make much sense).

I have the same concern. In my game I need the random boxes, it will be different on each game so that I can't pre modeled in Blender. Do you have any idea?

If I understand you, you want procedurally generated terrain(made of blocks). I found ArrayMesh works well & is fast, although it can be hard to use and is poorly documented.

I wouldn't use blocky or procedural terrain myself, but it's not my game. You might want to ask yourself why you want blocky & procedural terrain at all, usually you can create a much better experience if you make the terrain yourself (and I think blocky terrain is a little weird). But if you still want blocky & procedural terrain, I can tell you how I did it(it's sort of complicated).
