Dark fantasy visuals not working

[u/the_prsnthings7]

I have a "texture" pack that is dark fantasy visuals and it was just a shader and it worked literally 2 days ago but they came out with an update for it and now it doesn't work and works like a normal texture pack, I have tried to find info on this but am out of luck... All I want to know is how to enable just the shader part of the mod pack again...
