Yeah, that's the brick top texture when I was trying to use a different texture.
I see what you've done to it now, looks way better with the new size.
also, I understand if you don't want to, but, the "Better at BLB" thing in your avatar kinda bothers me, I mean, we both obviously know all the rules of it, I just prefer to spend less time on it so I can get the bricks done faster, while you take your time slowly creating the bricks
I create my bricks through programs, but as you can already see, thats not all I do, I spend my time perfecting it too
I don't spend my time creating the bricks that I do so people can look at it and say "eww, you made it in a program, that means its bad" I spend my time creating bricks so I can get them to the public faster, I enjoy seeing my bricks used in gallery builds and what-not
so if you could, please remove it
me and you aren't so different

this was created only using the BLB editor only to see if I was doing it right, and to position the faces
