GLSL Shaders Error

I’m learning GLSL to make shaders in Minecraft (to start in shaders domain) but I have an error when I launch the game…
So it’s a problem with my file “final.fsh” (“fragment shader”)

Here is the code:

Sorry, it’s too long ^^
I can set off variables by placing “//” before the “#define …” and when I put them before the #define MOTIONBLUR, all is ok… So it’s a problem with the motion blur, I think so :stuck_out_tongue:

Thanks you a lot :slight_smile:
