I am running a modded minecraft, going all fine but the shaders won't load when entering the end. The only mod in the end is Better End, but this doesn't seem to be the issue since it also occures without the mod. With or without Better End, the error seems to be the same as follow :
crumbling.vsh: crumbling.vsh: ERROR: 0:124: 'gl_FragCoord' : undeclared identifier
ERROR: 0:124: 'scalar swizzle' : not supported for this version or the enabled extensions
ERROR: 0:124: 'xyz' : vector swizzle selection out of range
ERROR: 0:124: '' : compilation terminated
ERROR: 4 compilation errors. No code generated.

Other shaders such as BSL or Complementary works perfectly fine, only Bliss is giving this error, which is sad since i find it's the best one as i know of, and the end looks amazing (not experienced it yet tho :( ).

After some testings, this seems to be an issue with an older version of bliss (DH compatible), i downloaded the latest one and it seems to work, sorry for inconvenience ^^
