Default swarovski crystal

hallo there! I canīt get the right material for a crystal shader. tried it with mr and maya shaders but all I get is a boring transparent object. googled the whole day but there seem to be very few tutorials for creating this crisp reflective effect when a light source hits the facetes from a diamond or something like that. also Iīd be curious how to split the white source light into rgb after the light rays crossed the material and step out as caustics. right now the light is monochrome + material is lame = §$%&

any help is much appreciated.

I saw that one after I created some diamonds a while ago.

I only reallly used a mentar ray dgs material and played with the settings and got the following pic.

I created the scene as I saw a animation of some diamonds dropping that someone did in mental ray and wanted to re-create the look of it (I didn't use caustics for the render as I didn't know how at the time).

If you want the material settings then give me a shout and i'll post them up.

heres the pic

whoa! material settings would be great! I tried with dielectric, but still not cool.

also what kind of light did you use? in case writing all settings down is boring for you, I would also take the scene itself to explore shader/light/rendersettings.

thx both of you!

for diamonds why don't you use the following:

dialectic material

col white 180 value (hsv thing)

ior 2.41

but you will never get dispersion (like color streaks and such), you have to use Maxwell or Indigo to get that effect

Whoops!

That will teach me to check the file first!

I'll have a look for it tonight and repost if you still need it?

still would be tremendous!



found the site

http://www.jeffpatton.net/Max7/


but cause of max has no node based architecture, itīs a bit hard to examine the shader network..
