trying to load a .cube LUT on runtime

[moebiussurfing]

hi, I loaded a .cube LUT and it works.
But I must hardcode the path into the addon class like this:

    LUTPass::LUTPass(const ofVec2f& aspect, bool arb) : RenderPass(aspect, arb, "lut"), lut_tex(0)
    {
		loadLUT("6.cube");
    } 

It's possible to load LUTs on the fly? Any idea?
