I am combining a few different textures into one 1024*1024 .jpg. ex. Bricks, shingles, windows, etc. It seems like an orderly approach.

Now, to properly texture a large face (rood), I would like to scale the selected image. ex scale the shingles smaller.

If I only have one texture within the .jpg, I am allowed to "Image Scale" the UV projection, to replicate the texture across the face. If I "Image Scale" my texture-combo ... it replicates the entire texture.

Is there a way I can "scale" within a material?
