These are the Achievement Icons for "Crystal Call" (soon to be released on Steam). I was asked if it was possible to make the icons look like they were carved into sandstone to match the theme of the game and it's temple look. Normally, I would just use Photoshop and fake the look, but I needed to deliver a total of 80 rendered images, and I knew that there would be changes and updates down the line. For that reason, I decided that it was time to use my knowledge of Substance Designer to create my icons.
The Advantages of designing this way are: Non-destructive workflow, Rapid iterability, Realistic lighting, and the ability to quickly see different random seeds and experiment with different looks.
The Disadvantage: it would be confusing for people other than myself to understand my nodes and make adjustment.
Conclusion: I will absolutely be trying this again on other projects and seeing how I can push this further.
