I'm stuck here, I have obtained an fx file and can't apply the effect to my level walls, here is what I have done.

I'm posting my question here as I think this question is very trivial for the shader forum.

1- I put the fx file in the same directory as my game studio script file

2- created a material block with an effect pointing to the fx file

3- tried to assign the material to a wall in my level from the block properties then clicked material icon but the list is empty and I can't find my mterial in this list.

here is the code of my script
