Quote - not sure if you can or can't.. but hint-hint-nudge-nudge for Paolo.. the ability to copy/paste acsel shaders to new textures.  like.. i have 2 models in my scene.. one has bree shaders and other has no shaders.. control/click all the bree textures and copy/shaders.. ctrl/click model w/o shaders materials and paste/shaders

You can do a copy/paste across models. That's how I transferred my V4 settings to the equivalent Gen4 Genesis versions.

There are usually only a couple of actually different shaders across a Genesis model anyway as the body parts (torso, hip, arms and legs) tend to have exactly the same settings.
