This first render is in Cycles and took a little under a minute.
This second render is with Eevee and took a couple seconds.
I plan on making an animation out of this, but I wanted to compare the two option. Throwing an irradiance volume in the eevee one I think helps a lot so I might go with that one.
Though I kind of like the meta of this template, so I'll see about turning it into an NFT.
