when I try to use this on my m1 mac in 1.21 with iris it does not work and gives this error

composite.fsh: composite.fsh: ERROR: 0:1: '' : version '430' is not supported
ERROR: 0:1: '' : syntax error: #version
ERROR: 0:2: '' : #version required and missing.
ERROR: 0:15: '2' : syntax error: integers in layouts require GLSL 140 or later
this is the log https://mclo.gs/SnOrMAw

Sorry that you got this error, this seems like a big oversight of mine. I made an update (V1.1) that should hopefully fix your issue. Find them on Modrinth or on Github. If you encounter any further issues feel free to ask :D

Thank you for your time I will test to see if this fixed the issue when I get a chance

ok I will make a new issue

so I tested and it gives a new error
