ExTile POM is now out on Fab.
It’s a parallax occlusion material function that lets you set the depth in centimeters, and it stays consistent as the texture repeats. Cracks and joints darken on the side away from the sun, and the shadow moves when you rotate the directional light. There’s an Optimization slider from 0 to 5 for surfaces that need to cost less.
It also includes the Generative masks nodes from XDP Pro and Extile Plus: Dirt, Leaks, Damage and Blobs, which you can blend between layers and bake to textures with the free Baker plugin that you can download on the product page.
