There's a LOT of lens flare in that animation giving it sparkle.  Lens flare is an artifact that is not going to show in a render.  Not saying a lens flare effect would be a bad idea for an optional filter in KeyShot, but the flare is created by the lens.

If you take a static screen shot of the animation, discount the lens flare, it's on par with previously posted KeyShot examples.

If those KeyShot examples were animated on a turntable, you would see much the same, except for the lens flare.

Ed does not work with large stones. I guess he can't seen

"The tune" goes something like this

try and do it in keyshot!!! and show us

QuoteABBE, HDRI, reduce pixel filtering...
LOL
I don't think that's good enough.

Keyshot diamond mat is underdeveloped!!
It stopped in the development with Hypershot 2008 :( :( :(

You think only of oneself, about wedding rings with spark diamond...


Quotesparkle, lens flare, animation...
Of course. Why do you need it

That's about it.


I have a sneaking suspicion that the Keyshot going to succeed  ;)

Hi all
KeyShot added new material gem in the 2.1
It differs from the old (dielectric) ?
I did not notice any difference ((((((((

In what, essentially, lies the difference?


KeyShot

It is easier to understand. The old solid glass was used for both liquids and gems, and it made more sense to made dedicated materials for gem, glass, and liquids. The dielectric material is indeed the old solid glass.

I used black and white HDRi




Abbe number 10
Ray bounces 30
Pixel filter size 1

Nothing changed
The brown (dirty) color is still here


KeyShot

If you can send your model and hdri to support@luxion.com then we can take a look at it.

Johnjoti

I send you model and HDRi

but diamond should look like this:

alternative soft


or



HDRi


Thanks

Am I being a bore?

Ok I will not press the point  :'(

John,

Here's an example of the high contrast and richly colored dispersion type diamonds, like you had posted above.

20 ABBE


10 ABBE


For this effect you just need to keep your realtime gamma low and adjust the ABBE. Also adjust the brightness and gamma of the environment itself for further control.
