Tried dropping this into a pretty hefty modpack and the Clear Pipes don't seem to render correctly. Are there any known incompatibilities with other mods that focus on rendering/optimization?

I just noticed this myself yesterday. It looks like it broke when the Fusion mod updated. Not sure why yet. The last version I know it works with is 1.1.1a

Talked to the Fusion dev. It looks like this is a bug with Fusion 2.0 and up. Keep an eye out for an update to Fusion.

Good to know! Thanks so much for looking into it :)

Fixed in newest version of Fusion
