Variation in all tiles

Tiles of all kinds should have a few variable textures within each set so they appear natural instead of the same patter repeated. This would be great when you have cobble stone, dirt paths, etc. Even within paving stones, though the stones are laid in patters like basket weave, fish bone, soldiers, etc., the stones themselves vary enough in tone and sometimes color blends that the repeated pattern blends with itself and does not have square like outlines as the tiles in this software has.

Wall tiles could vary in use, age, some coloration, etc.

It's a really cool VTT, though.
