I have a plane mesh in Unity. I have various other meshes on this plane (props) with tags that denote the areas under these props are unwalkable. I raycast, project and generate a grid on this plane and I have a map of walkable regions and unwalkable regions. This grid is a List of GridCell objects, I'm omiting the details.
Now I want to visually show this grid, so I attach a mesh renderer to the Gridcells and attach a mesh. Looking good.
My question is, can I use 2D sprites for these cells instead of a 3d mesh and still get the visual overlay on the grid plane?
