Is it possible to reload the shader files while in game, sort of how you can do in Iris? I've noticed there is something called ReloadableShaderEffectManager but I couldn't figure out how to use it. I've also tried reloading the resources with F3+T but it did not have any effect.

I might be missing something but this would be great for iterating on an effect until you've got something you are happy with. Thank you for making this mod and good luck with the port to 1.21.2!!

Found the answer in the Ladysnake discord:
