I only tried it out for a few minutes, but in general the demo makes it look super promising. I’m sure with a little extra work, the output could be converted to use SparkSL or the Lens Studio shader format.
Also seems like a good source for learning / inspiration via the community submissions. You can explore graphs created by other users!
Another cool feature is the live shader output. You can see the code that gets generated as you are working!
It’s pretty easy to share links for collaboration too!
