I did as you said: I included the mtlFX at the beginning of my game script

Code:
#include <mtlFX.c>;


and then I made an action for my entity:

Code:
action test()
{
my.material = mtl_toon;
}


and also the mtlFX.c and the rest of the shaders are in the game folder. But when I try to compile I always get this error


Help plz
