What happened?

CPHSBC shader by CrushedPixel (link to vid: https://www.youtube.com/watch?v=zgGl-xLlOcs&t=1s)

Iris seems to render CPHSBC shader differently to optifine, where less shading is present and the block breaking animation is fully opaque and dark instead of having transparency. This might not be worth looking into, but I would appreciate if you did or are able to suggest a remedy to the issue, thanks

No response

The black block breaking animation is still a thing even with an empty shader to trick Iris into using "New Lighting", so this black block breaking animation thing is not specific to this shader, however people have managed to find a way around this by adding code into their shader to mitigate this. This is still true on 1.20.4. @IMS212 please investigate this thanks.

This is already fixed in the next version of Iris
