Title: Fine Jewelry Realism - give me your feedback! Be critical please
Post by: Spydabizkit on October 08, 2019, 06:17:27 AM
A couple more images from some projects I've been rendering lately.  I should start dumping these regularly to speak up some conversation.

Let me know your thoughts!

Looks great! My favorite is 97FDE597-A23D-4401-81F5-29F390F3429C.png. What modeling software are you using to create these? Did you use any extra passes to generate the final or is it straight out of KeyShot?

Thanks Chad,

I'm using Matrix 9 to model these.  Besides the first image, all of these are straight out of Keyshot with no other editing.

This is an example of one I edited after in photoshop

Backdrops are easy to work with though if you use the photographic image mode in Keyshot.  This one is Keyshot only too.  No photoshop.

Not really a fan of jewelry renderings but I have to admit these are gorgeous!! I especially like the last one in the first post!

These looks really, really nice. Loving the mood and the composition of the last two shots. Just perfect.

Thanks so much everyone.  One thing I find difficult is to find images or backgrounds that make sense for use in keyshot. 

There is still so much to learn too.  Everyone on this forum is so helpful and the wealth of knowledge within these forum pages are insane!

Nice ! I always prefer the in-context images even though i know it isn't the best way to go in most of the cases. But i can't help to tell a story in every image.

Really beautiful work!

My favorite trick for a ground is to use a plane created in native CAD, not the KeyShot plane, with the underside mapped in one color and the part itself in another.  Then, in KeyShot, apply say "chrome" to the underside, and "frosted glass" to the part.

Then you can tweak the ground to suite.  Of course you can use any combination of materials for different effects.

See attached...  for this I used a "pebble" bump map.

Hey Bill ! I remember hearing this technique before. What are the benefits of the dual planes when compared to, for example, a single plane with a chrome material and the pebble map ?

I like the dual surface ground plane as it allows me to apply chrome, brass, etc. to the underside, and then frosted glass to the top side.  Then you can tweak the glass roughness to vary the reflective and shadow qualities.  Below is an example using gold underside and frosted glass with just a tad of a wavy bump.

Of course you can also add a bump to the top side material, which can be whatever you want, including glass, my favorites being pebble and wavy.

Nice!  I will have to try that, and mess with a couple of settings.  I am curious as to if the same look can be achieved with a "Multi-Material" created in the material graph.  Something with a clear coat, or translucent coat with bump applied.  You can definitely go down the material graph wormhole and come up with some interesting materials.  Your renders look great.  I think I actually downloaded a physical light scene from you at some point, but haven't got around to mess with it too much.  I'll have to open it up and play around with it.  Thanks for the tips  ;)

I avoid the "material graph wormhole" as much as possible, usually choosing a simple and repeatable solution.  That's why I like the two-surface trick, and use it on many projects from jewelry to medical devices.  It's simple, yet very flexible.

Here's an example using "black chrome" underside and a lightly frosted glass on top, with no bump map.

Think of it as a back surfaced mirror.  Tweaking the glass qualities is the trick!

Those look fantastic.

Did you model the curb chain?

That is absolutely beautiful.  Where might I find the information about the two surface trick?

These are truly some of the most impressive jewelry renders I've seen on this forum, exceptional work +1
