I installed the GLSL Shaders Mod for Minecraft 1.5.2 with Magic Launcher.

When I try to open a ShaderPack(SEUS v10.0, I get a message:

"[Shaders] Error: Invalid program gbuffers_textured_lit"

and a red screen(See Screenshot 1).

But with another pack(SEUS v10.0, it gives me small, blue screens in the bottom-left corner(See Screenshot 2). It also gives me the message:

"[Shaders] Error: Invalid program gbuffers_textured_lit".

Screenshot 1: screenshot 1 Screenshot 2: screenshot2 Anyone knows how to fix this?

I am using Windows 8 and Minecraft 1.5.2 (While using Magic Launcher for mod installing).

What version of Minecraft did you install the mod on? – RavenM Dec 24 '13 at 19:14
minecraft 1.5.2 with magic launcher – nelson2tm Dec 24 '13 at 19:24
Could just be my imagination, but could this be a library that should be installed/is found through another installation method of these mods? – Cole Busby Dec 30 '13 at 17:18

Change line 47 in composite.vsh from 'float timePow = 2.0f;' to 'float timePow = 3.0f; Changing it will get rid of the Invalid Program Composite error.


Possible change for Minecraft 1.6.2, may work for minecraft 1.5.2. Let me know if this helps, I'll keep looking otherwise.

I have reinstalled all packages, i have changed 'float timePow = 2.0f;' to 'float timePow = 3.0f' and i get even more errors (even with unchanged), with dome packs it works, but with SEUS v10.0 not. errors: invalid program invalid_textured_lit and invalid program final. – nelson2tm Jan 5 '14 at 11:53
