This Alien Doesn’t Exist - devlog 1
👽
I’ve started working on This Alien Doesn’t Exist, a procedural generator that creates alien lifeforms from a single seed.

The idea was inspired by This Person Does Not Exist, but instead of AI, every creature is generated entirely through code. Enter the same seed, and you’ll always get the exact same alien.
⚙️
So far, I’ve implemented the core generation system. This includes seeded procedural generation, body generation using a spine and signed distance fields (SDFs), procedural limb generation, and basic procedural lighting and coloring.

One thing I wanted to avoid was stitching together pre-made body parts. Rather than choosing from a library of heads or legs, the generator actually creates the creature’s anatomy from scratch.

The next step is making the creatures much more diverse before moving on to things like eyes, skin, horns, and other anatomical features. Hopefully by then they’ll start looking less like blobs and more like actual alien organisms.
