swarovski crystal
 
hallo there! I can´t 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 I´d 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!

Here you go, its in Maya 6.0

Hope it helps you out.

Falott 30-07-2006 11:46 PM

thx for your file! but could it be you posted the wrong one? cause there is a gravity field and rigidbody nodes but nothing like diamonds. ':)

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 ;)

Falott 31-07-2006 01:07 AM

do you know a method of dispertion fake for mentalray?

I´ll try with your settings, thx!

MattTheMan 31-07-2006 01:39 AM

nope. far as I know it's not possible :(

Falott 31-07-2006 06:38 AM

I recently came across a site explaining a dispersion fake for mental ray in 3dsmax, but didn´t bookmark it. dang!

gster123 31-07-2006 06:46 AM

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?

Falott 31-07-2006 07:16 AM

still would be tremendous!



found the site

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


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