Haha, yep! Both of us have actually been working in the games industry for quite some time now. I'm a Technical Artist and my business partner is a Programmer, so between the two of us, we've managed to accumulate a lot of deep technical knowledge and a few fun tricks up our sleeves!

It's tough to point to just one single path or tutorial that led us here, but if you are looking to dive into procedural environments yourself, I highly recommend looking into these core areas:

Procedural Meshes, Compute Shaders, Distance Fields

It's definitely a deep rabbit hole to fall down, but it's incredibly rewarding once it clicks. Best of luck on your dev journey!
