Finally had some time to sit down and look over my concrete texture in Substance Designer. I recreated a system for cracks in the concrete and improved the grout lines. This makes the concrete feel more natural. My Substance graph is messy, but I tried my best to keep it manageable. It's pretty simple for me to go in and change two variables to get all new cracks. This is great for making final adjustments towards the end of the scene.
Now time to get busy with the other assets!
