Layer Painter
Layer Painter is an addon designed to change the way you work with materials in blender. It takes inspiration from 2D software and programs like substance painter to provide you with a layer system and all the benefits that come with it.
However the point of layer painter is not to replace blenders node system or other texturing software completely, but simply aid you in getting quick results for your materials. It also allows you to keep the texturing part of your workflow in blender and avoid constant importing and exporting.
