Is your feature request related to a problem? Please describe.
I would be cool to have Canvas shaderpacks work with this

Describe the solution you'd like
An extra mod, or a optional toggle that allows you to use Canvas mods with this

Describe alternatives you've considered
A separate mod, that works with Iris.

I feel like this is already handled by canvas...?
