All the steps are in the screenshots

USE WITH THE GLSL SHADERS ONLY WITH SETTING BUMPMAPPING OR BUMP-SHADOWS!!!

Get the Nvidia Normalmap filter Here

Also this tutorial is made by Daxnitro the crator of GLSL shaders to fix the missing bumps on 256x
THIS IS REQUIRED FOR EACH TEXTURE PACK YOU WANT BUMP MAPPING ON!

1. Navigate to your Minecraft.jar/shaders folder.
2. Open the gbuffers_terrain.fsh file (can be done with any text reader, like notepad).
3. Find the part in the file that says this (the 64 and 256 part will not be there by default, add it if you are using 64 or 256 resolution textures):

//const vec3 intervalMult = vec3(0.0039, 0.0039, 4.5); // Fine for 16x16 tile size

//const vec3 intervalMult = vec3(0.0019, 0.0019, 0.5); // Fine for 32x32 tile size

//const vec3 intervalMult = vec3(0.0009765625, 0.0009765625, 0.145); // Fine (presumably) for 64x64

//const vec3 intervalMult = vec3(0.00048828125, 0.00048828125, 0.2); // Fine for 128x128 tile size

const vec3 intervalMult = vec3(0.000244140625, 0.000244140625, 0.1);// Fine for 256x256 tile size

1. Remove the // from whatever line matches the resolution of the texture pack you are using.
2. Add the // to the texture size you are not using (there should only be 1 line without the //)

Note: IF this arent a studio release by your thought. post a comment instead of flagging it directly
