How do I randomise a glossy node's roughness within a specific range? I have a glossy node with the roughness set to 0.05. I am using this material on many objects, and want to randomize the roughness by a small bit on each model (to be specific, between 0.02 and 0.05). I know that the way to randomize is to add an Object Info node, but what should I put between the Object Info node and the Glossy node to put the values 0.02 and 0.05 and plug into the roughness?



Thanks in advance!
All that is needed is a bit of math:



With an input of 1: 1 * .03 = .03, .03 + .02 = .05
With an input of 0: 0 * .03 = 0, 0 + .02 = .02
