Voxel Engine by ProceduralMesh - too much calculations?

Don’t create a separate section for each cube, you can just build the geometry (vertices and triangles) for all the blocks and send it all in one CreateSection call. CreateSection is expensive

You’re making 36 vertices for each cube. You only need 8 to draw a standalone cube. If you’re drawing lots of cubes in a matrix you need even less because you can share the vertices between the cubes.

At first I actually wanted to build them using just 8 vertices for each, but I don’t know what functions of the procedural mesh component could help me achieve this. I mean, is there a function which takes 8 vertices and returns a cube?
Or should so I take a few steps back and try to setup everything with, for an exemple, OpenGL?

EDIT: just realized I can effectively build such a function by calculating the 8 vertices and then build triangles from such vertices lol (if there’s still a better way, tell me please )
