The Shade Sewn Data converts all custom UV Maps created by other tools in the pack along the edges or objects where details were added to seampuckering, stitch crease and more that you can use as color or bump data in your shader. As custom UV data needs to be created separately in each tool, you can combine several of those attributes by chaining this nodegroup.
Inputs #

The custom UV Map generated by other tools on which you want to add shading details.
