Where is the world.fx from wolrdandnormals module of image.pack?

the world.fx inside the module is always red.can’t find in the folder.
and i checked elliot’s git.it doesn’t have it either.
so where should i find this fx?

i’m having this same problem! Did you ever find a solution?

Anyone got any ideas as to why this file is missing? Or where can I find it? Or could anyone send it to me even?!
thanks x
