What i usually do is just get the map and plug right in to the "material node's spec". However, the problem is, i don't have the controls to control how much weight that i want to apply to my object.
Then i tried using intensity node. well, it helped. but when i plug the "spec map" to "intensity" to "material spec channel", it turns my spec map to black and white. so that all my spec will becomes white.
How do i make it, what is the proper way to apply a spec map.
