I want to use the Iteration Shaders but Minecraft wont let me.Other Shaders work btw
Im on Fabric 1.20.1,Iris,Modrinth.
When i try to apply the Modpack,it wont work and there is the error code:

moving_block.fsh: moving_block.fsh: ERROR: 0:201: 'texture2DProj' : no matching overloaded function found
ERROR: 0:201: '=' : cannot convert from ' const float' to ' temp 3-component vector of float'
