Perhaps its a limitation, and also a big chance I dont fully understand whats going on under the hood.
But wouldn’t a “Texture Coordinate node parameter”-(whatever-it-would-be-called) be handy for material instances?
sure I can mat-function a workaround, or make sure all the meshes are set up so I dont need it.
But sadly… sometimes you do want to adress different uv-maps on the same mesh in different occasions.
Would this be possible? and if so… would this be a suggestion worth considering?
so, extreme TL:DR
A Texture Coordinate Node that allows me to change the targeted UV-channel in the material instances.
