Realistic Diamonds?

Hi guys, I'm trying to find out how to make a realistic looking diamond in lightwave. I know it is possible because I have seen some renders of them before, done in lightwave. However, I been having problems in finding out resources, and tutorials to do this. I would appreciate any help that you may give me in order to make this happen.

Thanks

I know it's a plugin, but spectrum would probably help:

Thanks..but..
I forgot to say I want to create it using merely fprime.
I saw a tutorial some time ago, now I can't find it.

are you looking for modeling or texturing/lighting info?

I guess that both, but more importantly the surfacing.
Maybe both are related to give a nice realistic result...?

Dave Jerrard had a tutorial about diamonds. The site is down now. But I read somewhere that the tutorials are hosted somewhere else now.

And there was a nice tutorial about gems in a back issue of Keyframer Magazin.

just out of curiosity, have you checked that ice diamond thread plugged at the top of the main mage with those amazing renders of ice? I know it's in MAX or whatever, but he used very basic, very fast techniques to make that ice. You may want to check that out if you hadn't.

Modeler has a built in Gemstone Tool (Create -> Primitives -> Gemstone).

I did this a while back with the gemstone tool. I just used lots of refraction and specularity and maybe a good HDR for added reflections. It's never got 100% realistic but with more work it would work pretty well. I think some good post work would help with gemstones, too.

Thanks a lot for the replies!!




I don't quite understand his little tutorial.

What I can get from it, is that he used a planar surface on the back, he made it invisible to camera. Then he putted 100% refraction to the object (how does that translates to lightwave?). He also used an hdri to light it up. I can also see that he used a bumpmap to make it look scratched.

Whoever wants to jump in an eaxplain to translate this to lightwave is welcomed. I'm pretty bad with texturing.

Don't forget to make your air layer!

Yup, almost forgot that one
So what I understood from the "little tutorial" was ok?
