I was working on a larger scale Layered Master Material, found myself using Break and Make Material attributes quite often but for simple things, would be nice if this was a lot better handled. Clicking into the existing material functions such as MatLayerBlend_Emissive you can see this break/make where all lines are passed across, seems unnecessary.
Resolved pretty quickly! Lauren Ridge informed me of the ‘Set Material Attributes’ and ‘Blend Material Attributes’ nodes that were added in 4.14. Thanks!
