I have continued to work on my entry for the Allegorithmic's Materialize contest. Just a couple of days left before the submission deadline, and still quite a bit to do. This is by far the most well composed Substance I have ever made. I took extra time to organize it as logically as I could, isolating features of the material, and building them in step by step.
I'm much happier with the look of the marbling of the paper mulch than my previous renders. It took a great deal of experimentation and learning to get to the right result for this material. It's not perfect yet, but I hope to fine tune it even further in the next couple of days. I will also be doing some production renders of the final material and brick object, which is not required for the contest, but I love working in VRay and it is a minimal setup, so it will make the project feel more complete.
I haven't quite got the right colours yet, and still need to work on the marbling of the paper mulch, but it's getting close. I will do a full breakdown of my graph when I'm finished.
