@mattshumer_ The interesting question is what happens to 3D asset tooling companies when a model can generate custom ThreeJs environments on demand. Middleware that sells 3D asset pipelines is looking at a very different competitive situation than it was a year ago.

@SimonasLTU1 High, just use /loop with a strongly-worded prompt. This took less than an hour.

@mattshumer_ Wtf seriously? Wow. This is the first time in a while I've been seriously impressed by a new release in that case. I've had a lot of "wow nice!" And hype moments but it's been a while since something was truly impressive

@mattshumer_ Was this on Max? I didn't try anything on max, but tried on Extra High and nothing was this good. How much did it cost if it's not a secret?

Insane is an understatement @mattshumer_ 🔥 Fable just turned browser-based 3D worldbuilding into something straight out of sci-fi — all with custom Three.js and a few lines of prompt? As an AI & code enthusiast who basically lives in the “first employee” grind, this is exactly the kind of tool that lets us build immersive prototypes at warp speed. Huge implications for rapid startup MVPs and next-gen experiences. Mind officially blown. What prompt did you use for this demo? Would love to experiment tonight 🚀
