With SU 7 now,on top of all, you can always right click on a face and make the texture (no matter it is tiled or not) "unique" then again, from the context menu > Texture item, you can select to edit in an external editor and give whatever effect you wish to only that face (but the whole face).

Quite handy IMO.

2 Gaieus: Can i ask u, how this "make unique texture" affects the filesize or how it works? I am not only one who is having LARGER filesize after using this feature...Thx in advance
