@poopipe Thanks for the reply! I Asked him in the youtube comments and he mentioned he just made the geo in Houdini and using a spherical mask in Unreal to mask it out.
Hey, Trying to recreate what Simon Houdini has done in this tutorial in Unreal - Rendering only what's inside a sphere and culling everything outside of it, but kind of at a loss. Does anyone how he has done this? It's exactly what I'd like to implement in a mobile game im working on. Thanks!
