Match a Bump Map params to Diffuse Quickly?

[M V]

Any way to make a bump map UV parameters match that of the diffuse in one quick shortcut?

What do you mean...if you create the bump from the diffuse map and use UVW mapping it should match perfectly.

You can add a float controller and connect that to various parts of the bitmap. This video explains it better than I can describe it. I learned about this at the CGSchool class in Boston last month, but haven't really explored all of the possibilities of it yet. For instance, you need to do some math if you connect the float to an angle input or if you turn on Real World Scale. Perhaps there's a better option, but this is an easy way to instance the UV values of multiple bitmaps.
