The "universal" wood material I made in Designer, I got to test it's functionality in Painter. The material can generate wood that's clean, and also age and crack the wood. That includes the painted surface. A map that can be anchored drives the aging of the wood and paint. Because the material is complex it can be a bit slow, but adding anchored image is quick and the material performs all the aging.. The wood grain too can be referenced as it will convert a simple gradation into a wood grain using a curve function. Though it many ways this can save time vs setting up a layers of materials in Painter. This has an extra bit of cohesion with the weathering and aging of the wood. Though, there are limitation to referencing images into a Designer material. If you rotate the SD material in Painter the anchored reference doesn't rotate with the material, so I have to put in a safe transform to fix the reference anchored maps, and it only works in 45 degree angles. So it's a limitation to referencing maps, but it still is workable, as you can see.
