I think the title says it all, but anyway....

I have a head texture and a normal map all made for it. Anyway, after playing around a bit i found that id like to tile the bump map a bit without tiling the texture.

Now for all who say, just tile in photoshop, my problem there is that i dont want the bump map size/Kb to be any bigger. Is this just a wish list request, or am i just missing something?

thx for the help
