Tiles, unable to achieve correct result

[gelbuilding]

Hi,

When i need to make tiles to a specific texture i take a picture of one tile and give it a bit of variation with the file that i have attached.

I dont understand why i have different results from the created sbs.
The tile is 600x300 though you see there is a grid showing the tile with little tiles inside.

File and image attached.
Any help would be greatly appreciated.

What engine is this? The floor looks fine, it's just the walls that have the repetition. My guess is that somehow the wall material was set up with your tiles being set as the regular maps AND detail maps, instead of just regular.
