Forge 1.8 crashing with Shaders mod

[Vinegar]

Hello, I have a problem with forge and shaders. So, whenever I join a server or world, my game crashes. I have shaders on and no other mods. Here is the crash report:

The game crashed whilst tesselating block model
Error: java.lang.IndexOutOfBoundsException: Index: 2, Size: 1

 

I am using Forge 1.8 and shaders mod 1.8.

This is the shaders mod: http://shadersmod.net/version-1-8/

Forge version: 1.8-forge1.8-11.14.4.1577

Shaders version: ShadersMod-v2.4.12mc1.8

Why are you using 1.8? It's ages old and outdated. Use 1.12.x. Or, if you must use 1.8.x, at least use 1.8.9.

 

This is most likely an issue with the shaders mod and you need to talk to them.

Should I use the latest version or the recommended version of 1.8?
