I did search - honest - but couldn't see this problem.
I am not worried about this as i can understand photoshop brushes may act strange and might not be compatable.
I have recently got some great tutorials at stupidly cheap prices from Aaron Blaise (creatureartteacher)
I have got a lot of his brushes and then work just fine.
I have a couple of sets (cost $1 each that , when i go to use them, i get 'bands' across the page and not always in the same place.
I can't see where in the edit pages this could be adjusted and it could just be that they are incompatable
There's about 3 sets, but as the tutorials i got were also $1, i am really not worried if they don't work
I'm asking the question just in case someone has sorted this problem out.
They are all later ps brushes
I have attached image here to show what i mean
thanks in advance
