What happened?

A made a small mod that makes the vanilla game's takePanorama() method usable. It works as intended but however as soon as I start using IrisShaders the six panorama screenshots just show the sky color. When testing I was using no shader pack. The method is located at net.minecraft.client.MinecraftClient.takePanorama()

The vanilla method could need re-implementation to ensure that all the needed Iris state is properly set up. One complexity for high quality panoramas is that it is likely necessary to render multiple frames at each perspective to give time for things like temporal anti-aliasing to settle down and give a properly anti-aliased image. This is similar to the issues with Immersive Portals where AA can't settle down as easily in some cases since it's effectively the camera jumping back and forth very fast from the shader pack perspective.

So... Fix in next update?

Unlikely as the only current active developer of Iris is IMS212, and they are focused on other development work.
