What to use for flat grid-like ground?

@HorusWM

To render tiles use the Hierarchical Instanced Static Mesh and check coordinates of characters according to the corresponding tiles grid in the form (loc * grid size) / grid size. For grid data use the structures array.

Took a look at Instanced Static Mesh, looks promising, although I couldnt find much documentation on it, especially not in C++ so that might be a problem. Any links?

As for the grid data, should I use Data Tables?
