I recently saw a video showing off SonicEther's Unbelievable Shaders Mod, and I thought it looked cool so I tried to install it.
I followed a few tutorials, and the steps I took to install it were:
Installed Forge for minecraft 1.7.2, no errors.
Installed GLSL shaders mod for 1.7.2, no errors and show up in-game.
Put the Shader pack in the shaderpack folder (clicked open shaderpacks folder in minecraft), no errors and the shader pack shows up in the selection menu.
But when I try to go in-game and look at it, I get the glitch shown in this video. I tried installing 1.6.4 with the same steps, I got the same error. I couldn't find anyone else with the error so I eventually gave up.
But, I really don't want to give up on this mod. I'm hoping someone knows how to fix this.
