I tried installing the GLSL Shaders Mod, but no matter what I try, it just uses the default lighting. I'm using Minecraft 1.5.2 with Magic Launcher 1.1.4 and I have these mods installed (in order):

  1. minecraftforge-universal-1.5.2-
  2. OptiFine_1.5.2_HD_U_D3
  3. ShadersMod-mc1.5.2-ofud3-1.46
  4. [1.5.2]ReiMinimap_v3.3_05
  5. JourneyMap2.6.0_MC1.5.2

I have installed shaders, none of them work.

    This is an awfully useful question, I've struggled with GLSL to no end. A shame the question will soon be obsolete with Resourse Packs and stuff, but I'd still deem it valuable.

The Shaders Mod just adds code to use shaders – it doesn't bundle any actual shader files you can use. You have to download a shader pack now, and there are lots of different ones for different effects and tastes.

For example, here are my shader packs.

To install shaders:

  1. Drop them into the shaderpack folder located under .minecraft
  2. Start Minecraft
  3. Go to Options, click Shaders, and select the pack that suits you
  • I guess the shaders I found didn't work. Thanks for sharing all of those shaders.

  • What do you drop in the .minecraft\shaderpack folder? The zip file itself? I extracted the 21 zip files from that linked rar, and placed them into the .minecraft\shaderpack folder. No Shaders button appears under Options. Some people say the folder should be called shaderpacks (plural). But putting the zips in a shaderpacks folder doesn't work either. The rar contains a shaderpacks folder. Should it be .minecraft\shaderpack\shaderpacks\*.zip ?
