The Substance model graph seems intimidating at first, but it is, much like the other tools in the Substance suite, interesting and intuitive. Model graphs do seem to have a bit more of a learning curve, but can definitely be picked up quickly. I really enjoyed trying out new strategies and developing this procedural castle wall model. The height, wall width, and wall segments are all variable. The whole experience was informative, and I definitely intend to continue exploring this toolset.
