Going to share few shots from a little hobby project I’ve had in Unreal. Fractal rendering tool, done entirely in a single custom material expression.

Incredible! Reminds me of [Light, shadow, and fractal patterns in "emergence" | Unreal Engine - YouTube](https://www.youtube.com/watch?v=5KqTv8ibNRQ)

Would love to see video of it in motion (that top one in particular), and possibly more details of your implementation… this stuff is like black magic to me 😉

Missed your response for some reason. It is not realtime and rendering speed entirely depends on complexity of the fractal, varying from 100 to less than 1 samples per pixel per second at 4k. Implementation is simple blueprint draw material to render target with a material, that has entire path tracer coded in custom material expression.

Hi @Deathrey

Looks Amazing. When can I get my hands on this?

Hey @Deathrey, this looks incredible, is there any way we could make a deal to test this out?
