Jewellery rendering

or if you want to stick with McNeel and are on Windows … Brazil:

exactly as quoted above.

I disagree as Brazil is discontinued by the developers and not something to invest time in IMO.

Maybe, maybe not?

Brazil will be an inbuilt plugin in rhino6??

V-Ray 2.0 definitely makes you start reading stuff like this very soon. Results can be very good, BUT the plug-in itself (right now) simply cannot be considered ‘very good’.

Maxwell’s results are very nice. Personally I don’t like the plug-in for Rhino, I don’t like the material editor, and Maxwell Studio, the standalone version, crashed often. Also, it is really not fast.

There are updates coming soon for both though…

Right now I am testing Thea. Not sure about results yet, but the plug-in itself is very nice: A proper, modern, finished product. But I guess top-notch results can also make you kind of a raytracing, biased, unbiased guru first…

I can recommend thea. Using it for jewellery for years now. Easy setup and rhino plugin is a blast.



Cycles will be - and might be enough?

As for a conclusive answer to “which one is the best” - there isn’t one.
A lot is about personal preferences - so try before you buy.

Unbiased might be easiest if you want physically correct results without a lot of fuss (but perhaps with a good bit of waiting) whereas a biased engine will allow you to go beyond realism and insert artistic freedom but requires in-depth knowledge of the settings…

This images looks quite realistic.but if I want a black background is it possible to get that??
Also thea works as a plugin for rhino??

You can choose whatever you wan’t as a background. Yes, it works as a Rhino plugin as well with interactive render viewport and full GPU support

Here’s a simple setup and a simple ring I just made in Rhino 6 WIP.
Rendered with the built in Cycles Render display mode.

As you can se it lacks dispersion and other advanced features for a realistic look. But can be good enough for simple presentations.

Why do you not considered 2.0 ‘very good’ ?

Hi @matt_newberg,

I hope I am not saying something wrong now, because I’ve uninstalled the demo version and cannot double-check…

  • The plug-in often has a response time like a mobile website or so. Not slow, but like there is sth. between V-Ray and Rhino.
  • I think there was just one preview scene for materials: The sphere
  • I think you can just load .vismat files, but not popular .vrmat files (Did it come with a bunch of standard materials?)
  • No clipping planes. (I remember me finding out I need to create a double-sided material in order to look inside a small room …)
  • What is called ‘Lock viewport’ in Thea is something I was missing or I just couldn’t find it.
  • When you load a preset file into that Options window you cannot see which file you loaded or that you loaded a file at all.
  • When you change values in that Options window you cannot see which values you changed.
  • I think the windows were not dockable? (I often ended up having Materials, Options, Rendering, and the small progress window open and then things look like a mess.)
  • I had a demo version and render channels didn’t work at all. That’s okay if not having a license was the reason, but there was no feedback telling me so. To be honest, I still don’t know whether I did make something wrong, but just adding render channels as shown in the manual simply didn’t work.
  • I have a Xeon E5-2670v0 and, well, perhaps V-Ray RT is super fast with a GTX 980 or so, but for me it often felt like: This scene and this CPU cannot be the reason why V-Ray RT is not faster now.
  • I had to change a value in vrayforrhino.ini to prevent freezes: gui_timeout_minutes=5. (Which I found out at a point where anger played a role…)

One thing that in my opinion also really gets into user’s way is: When you learn a piece of software like V-Ray you use Google and end up on YouTube. And most stuff on YouTube is for V-Ray 3.x for 3ds Max. Which seams to be a totally different piece of software. That is frustrating, time-consuming and finally makes you feel like you are not in the ‘very good’ team…

I hope not too much is just plain wrong, because I didn’t carefully RT*M.

how to render a diamond using V-ray in Rhino 5.
Can anybody share some tutorial file or a video??
V-ray is just assigning materials or can put a diamond image and than assign materials??

Here is a good tutorial on setting up a nice refraction material for a diamond:

I don’t know if for jewellery in particular, but…I would suggest Thea Render.

Its unbiased engine is awesone!!!

And also its “Presto” CPU+GPU engine is superb and fast as a lighting bolt.

I use it almost everyday and It’s perfectly integrated in Rhino V5 with its plugin.

Nice day,

Awesome renders man. Love them.

Thank you :slight_smile:

Has anyone the tutorial, how to create photorealistic diamond in thea plugin?

hey there!!! hope you’re well… I wanna know if there is any way to export rhino files into cinema 4d or Maya along with all the textures and rendering attributes ???

Sorry can’t tell, never worked with C4D nor Maya but I guess you can export geometry as obj file not sure about render attributes
