So right now the brush tool is kinda hard to work with pattern based brushes (Look at the elf wood floors for reference) and have them get aligned with the grid. They are always offset with the actual grid when resized and It currently difficult to do the offsetting (or resetting in this case) as the texture aren't made as a 1:1 with the grid size so not only do you need to adjust the size you want, but then work with both the offsets and you get weird numbers like 33.33 or 10.67 or 55.63 for your offsets.

Another issue I been seeing is how the brush texture "covers" the whole map already. What I mean by this is how when you brush, the texture is already predetermine. This can be seen and fixed by doing the offsetting of the texture. However this causes the issues of having 10+ of the same texture you got to look thru as they are all saved in your local texture pool. So if you want the current size, but say you want a 2x4 floor, you need to do an offset of the top and bottom and align both.

I can see a simple fix by making the a toggle where you can have the texture snap to the grid size AND have the ability to have them size them by grid size (Like how you can with the object). so it can start as a 1x1, then transform into a 2x2, or 1x2 and so on.

Also another thing that can be done to fix the predetermine texture issue is having the ability to either copy and paste a section of the background OR having the texture be moved with needing to do the offsetting.
