[SD5] Asphalt - Help/Critique
null
Hey there folks,
I'm learning how to use Substance Designer and I've just started out on my first tiling texture without the assistance of a guide or tutorial. I'm making some simple Asphalt, the kind you'd get on a road or runway. I think I'm heading in the right direction with it but something doesn't seem right and I can't put my finger on what it is. If anyone could offer any insight or feedback, I would hugely appreciate it!

You're on the right track, I think an adjustment to your AO would make a better diffuse than what you're using now. The first thing that jumps out is the roundedness and uniformity of the shapes. In contrast, the real deal is mostly a jumble of gravel mixed with tar, then flattened with a steamroller. There's a lot of variation in the shapes and angles you could take advantage of. And in other examples, we can see that it looks very flat, but still with the geometric shapes.
Something to consider is the size this will be viewed at, and any particular style you're working in. Asphalt generally looks pretty smooth when you're not really looking at it or driving by quickly, and in a game engine, too much fine noise just looks... noisy. Something I think that helps the most is the variation/stains/wear/cracks that happen. The GTAV image is a good example of the bigger picture when it comes to ground textures- high contrast, interesting wear, and relatively sparse rock noise. Hope this helps
edit: you'd think that at some point i'd have learned to remember to say what I wanted to say before distracting myself with mashing around on the keyboard.
In your original style and some of the less contrast-y images such as the tarmac one, it's easier to think of building up the substance as a height map first, and work out your additional images from that.
