Re: Custom attribute for refractive index

[Roger H. <rog...@mi...>]

I see that emissive colour has been added to the built in attributes. Is this because it could not be made to work as a custom attribute? I am having problems getting it to work that way, could I add refractive index to the built in attributes too? It would save some processing time for items which do not have a refractive index. I think over half the bits in the mask are free at the moment.
