Legacy GM Shader is not visible, when set too.

[Murr_]

So i was digging shader's some time a week ago. And now, i'm trying to do this thing <last topic ref.>. So i have a SURFACE which acts as a cloud atmosphere, which sets a shader (Gussian Blur) to make it more volumetric. (used Xor's shader for this, combined the x/y shader code together).

I have a global.gussian_CloudActive variable, to call if its activated or not. Regen fixes the surface if it is resized. When i set the shader along with the drawn BG it doesn't seem to add the effect nor show the BG.

        shader_reset();
        
    surface_reset_target();
   }
}

The problem is, that it's not visible. Possibly something having to do with the vec2 variables or the views that fix the resized surface. I don't know for sure. Any pointers?
