Hi- How do you scale down a shader? By that I mean: say you have a shader that is black and white squares (checkerboard)...how do you make the squares smaller or larger? Or with the corrosion shader how would you make the bits of corosion smaller to fit the scale of the object you are shading? Also can this be done if using a texture map as one of the channels (color, bump, etc...) I couldn't find anything in the manual about this. Thanks Daf

I think what you are looking for by scaling down is global scaling. Check it out and try, this will change the size. Dave

The Corrosion shader (if you're talking about the one that I posted in the free stuff section) uses multiple layers of cellular coloring and bumping. The same cellular pattern and scale is used throughout the shader. To change one means that you should change them ALL if you want the patterns and bumps to match up. To do that, first drop the the shader onto your object. Then go to the texture room and expand the various layers of the corrosion shader. Wherever you find a Cellular shader, adjust its scale accordingly. Hope this helps. Mark

Thanks Dave and Mark! I'm going to work with these ideas... Yes I was talking about the corrosion shader you made Mark, thanks!
