It gives me black screen can you please make a tutorial video in installing this mod.

Hmmm....
Alright, so it says there is a single error after adding the minecraftforge.zip. I tried minecraftforge for minecraft 1.4.6, and for minecraft 1.4.7. I am also using the universal version. Does anyone have any ideas for what to do?

Try install forge first then optifine and then glsl

A stacktrace would be easier than making a video. Try running the game with this batch file (written by me) and copy the output shown in the console. That will give us an error report and we can tell you exactly what's wrong.

This is a awesome mod keep it alive

karyonix, you not fixed feedback looping. Fix feedback looping, please!

Where is the feedback loop ?

Everything is jumpy when recorded with the minema mod.

I know it's not Minema's problem, I have tested it with separate Water Shader mods.
EDIT: It seems to be a problem with window size. When I play in a small window it doesn't jump, but in my 1920x1080 it does. The small window resolution is terrible, though.

I made a cel shader for use with this mod (link in my sig), going off of the old spec from DaxNitro's wiki. Everything works fine, except I haven't been able to find any detailed information on a.) how shadows are set up and b.) what functionality (if any) has been added or changed since DaxNitro stopped development. Is there any chance we could get a wiki or an api explaining things like available textures and their resolutions, which shaders handle which sprites, etc? I'll gladly help in whatever way I can, and I feel it would be nice to have a resource for other new developers.

I've been asking for this as well.

So this only works with Ultra Optifine?

I've managed to install the mod and it works, however when I play with the window maximized or in fullscreen I get this:

Everything on the right side of the screen is glitchy, any ideas on what's causing this?

my minecraft crashes everytime I play single player with this mod installed, it works fine in multiplayer though

karyonix, i cannot use anim "properties" for append animation to "_nh" texture. Fix it!

All bugs:
1. Texture appending does not working.

to=/terrain_nh.png
...

2. Feedback looping not fixed.

Minecraft GLSL ShadersMod v1.44
Information for shader authors.
=============
GLSL programs
=============
Each program is composed of vertex shader and fragment shader.
Vertex shader is read from "shaders/(program name).vsh" in selected shaderpack.
Fragment shader is read from "shaders/(program name).fsh" in selected shaderpack.
"gbuffers_basic" draw color without texture or light
"gbuffers_textured" draw texture*color : firework
"gbuffers_textured_lit" draw texture*color*light : particles and items
"gbuffers_skybasic" draw sky gradient
"gbuffers_skytextured" draw textured object on sky : sun, moon, custom sky
"gbuffers_terrain" draw non-semi-transparent blocks
"gbuffers_entities" draw mobs, players
"gbuffers_hand" draw hand, hand-held blocks, hand-held items
"gbuffers_water" draw semi-transparent blocks : water, ice
"gbuffers_weather" draw rain and snow
"composite" draw a quad on render target textures
"composite1" ... "composite7" draw a quad on render target textures
"final" draw a quad on final render target

=============
Render target
=============
There are up to 8 color textures that non-final GLSL programs can draw to.
These textures are attached to color attachment 0 to 7 of the frame buffer object.
Future ShadersMod version may allow changing the color attachment but not the current version.
Fragment shaders can specify which color attachment it will write to by using DRAWBUFFERS setting.
/* DRAWBUFFERS:???????? */
The first letter is target for gl_FragData[0], next is for [1] and so on ...
0 means color attachment 0, 1 means color attachment 1, ...
N means none -- ignore value written to this gl_FragData slot.
Please keep the length draw buffer list short for best performance.

The color textures can be read in fragment texture by using there name.
0: colortex0 or gcolor
1: colortex1 or gdepth
2: colortex2 or gnormal
3: colortex3 or composite
4: colortex4 or gaux1
5: colortex5 or gaux2
6: colortex6 or gaux3
7: colortex7 or gaux4

Default texture format is RGBA.
These lines in fragment shader trigger the change of texture format.
"uniform sampler2D gdepth;" : gdepth is RGB32F.
"/* GAUX4FORMAT:RGB32F */" : gaux4 is RGB32F.
"/* GAUX4FORMAT:RGBA32F */" : gaux4 is RGBA32F.
"/* GNORMALFORMAT:RGB32F */" : gnormal is RGB32F.
"/* GNORMALFORMAT:RGBA32F */" : gnormal is RGBA32F.

Clear
At the start of each frame, gcolor is filled with blue sky color.
gdepth is filled with 1.0.
Other color textures are filled with 0.0.

============
Depth buffer
============
Depth buffer used while drawing geometry is also available for reading in composite and final.
uniform sampler2D depthtex0;

I want to add a separate depth buffer for semitransparent blocks in the future. (not currently available)

==============
Shadow buffers
==============
uniform sampler2D shadow;
// depth buffer of non-semitransparent blocks and mobs and players
uniform sampler2D watershadow;
// depth buffer of semitransparent blocks -- including water, ice

=================
Vertex Attributes
=================
attribute vec4 mc_Entity;
// mc_Entity.x = block ID
// I am not sure whether vec4 is the proper type.

Wow, Karyonix, thanks for the fast reply! This is really helpful. Just a few clarifications: the gdepth texture is high-precision by default, right? What is the difference between the gdepth and depthtex0 textures? And if you're using a floating point normal texture, for example, do you have to put the "/* GNORMALFORMAT:RGBA32F */" declaration in all the fragment shaders that use that texture? Finally, what are the resolutions of each of the render targets? Is it possible to change these resolutions? Thanks again for posting this. I have a few requests and feature recommendations, but I feel like I've asked enough of you for now xD
