Specular Strength VS Layer Col VS Mask

Recommended Posts

Hi there


It seems like a Dummy question still I dunnot fully understand what difference there is between using the Specular Strength/Layer Col/Mask parameter to tweak a reflectance´s layer "impact" (at least when the reflection is uncolored). I can see some difference in lightness when using spec strength but Layer Col and Mask seem to work identically. Can anyone shed some light? I need some practical advise like "coated layer´s reflections should be modulated with SpecStrenght/LayerCol/Mask in contrast to... because..."


In this thread over in Substance Forum they advise to use the "strenght" defining textures  in layer color...


Sample Pics: left Texture in Specular Strength; mid Tex in Layer Color; right Tex in Mask Channel

Thanks for your feedback. That was somewhat helpful. "in most cases you´ll want to use the layer mask..." I´ll go for that and see what it brings. ..
