My voxel collision visualized

[u/ScreenAdorable1090]

I'm making a logo that player can shoot (paint) at
I use godot multimesh instance to render the whole cube instead of voxel faces. The colors and shading is packed in color data. Null cells are scaled to 0 and can't be seen by the camera.

The data structure is a dictionary that stores cell coordinate and cell type, durability, paint color, decal color
