[SUPPORT] Advanced Turn Based Tile Toolkit

Hi, I searched the thread but I may have missed the answer: How to scale grid size? Like, what is the official way of doing that? Because I want to shrink it to a very small level.
In a post you mentioned this could be achieved by adjusting the default tile static mesh, and you were going to give some formal solution to that.
Plus, I found “tile bounds x” and y in grid manager, but they are in “DO NOT EDIT” category.

Thanks in advance!
