Since 256 elements is way to much to edit by hand, so I ended up using a different way to finish the information at each point. Similarly, if youre representing certain materials, like insulators that have colored reflections (which are generally quite rare, and usually best represented with custom shaders for the typical ones like hair or iridescent materials) you will lose some information in the conversion process.
