Couldnt find Calcium carbonate in the ior.. how do i get it???

Would be very useful to have an .ior for all known substances, I can't find one [or an alternative ior solution] for travertine either..........

But travertine isn't a homogenous material...

Well it's a form of limestone, all of which are calcite in nature.

That looks great, glebe. Superbad from another forum showed me what I was doing wrong. My projectors were all messed up. Still playing with the coloring of the material now and I'll post what I come up with.

Also is there and IOR for Magnesium

U are right Grebe. My main idea
is get travertine, marble, sandtone, or limestone.
All them are based on carbon, calcium, and oxigen so we will need the IOR data to get the right materials. Will be great if they can come fron the next limit team.
