djflod - sorry for the delay - here are the screen shots;

long shot -
floor plane in dark blue,
lighting cube in cyan (back removed for this black studio, the white studio has the back included and needs to be set to 200% in multilight to blend seamlessly with hyltom's flooring material),
highlight lights in red,
'dazzler' in yellow
and ring in black!


medium shot -


close up -


It's not optimised at all but just thrown together but it seems to work. Hope it helps.

wow oz42.. great set of renders!

dazzler works great!

the only thing i don't like are the reflections on the metal part of the ring.
the hard edges of the multilight box disturb the shape too much, imho.

hmm..
you could try mxi emitters with polar gradients or so...

[oz42]

polynurb - Thanks. I know what you mean about the light edges, they are a bit too harsh. A good solution to the problem, I'll give it a try...

Does the light dazzler work with a white background setup? I've never been able to make diamonds pop on a white setup, just a dark setup.

Thanks for posting your screen shot Oz- I am wondering.... if either your box or your red emitters are not doing much? Do you have some shots where you are just using the larger Cyan box and then some shots with only the red emitters working? It seems like both can't be working because I can only see one round of reflections on your object. It would be interesting to run a test render and see what your ring(s) look like with those isolated. I really like the dazzler and am going to try that out on my next render. Here is a render of a scene that I finished a little while ago as well as some screen shots of my .mxi emitter light box.







The reason that I went for the gradient emitters is that I was having a hard time showing the dimension of the shape of the ring shank. I found that the gradient emitters really helped with that but the diamond suffered. I I read on the same wine glass tutorial about leaving some black around for the diamond to reflect but it is hard to avoid strange reflections on the metal and still achieve bright stones, I have found this light box to be a good compromise but I would like not to compromise . Thanks for sharing your setup... if we all did this imagine how great our knowledge bank would be ... Let me know any criticisms and feedback that any of you might have.

Blitzor - I've not tried it on the white background, I'll give it a go...

caryjames - on the previous page (1) you can see the evolution of the project. The first set of images (first post) are with just the cyan box, the second set of images (half way down) are also with the red emitters and the last set (toward the bottom) are with the dazzler as well. I agree with you on the use of the gradient .mxi emitter, polynurb has picked up on this as well and I'm going to try to throw that into the mix. Thanks for sharing your setup as well. I agree with you - it's how we all learn.

Hi Oz- I don't know how I missed that because I must have read your post at least 3 times ..... back to the corner I guess . I like your shots without the red emitters but that is just me. I am going to try the polar mxi gradient as someone suggested and also I am going to create a dazzler!! Are you using a preset for those emitters? Did you merge them into 1 emitter?

Thanks again for your work on this... I have challenged JD to come up with a tutorial for basic jewellery lighting. I know that Blitzor and at least one other person have it knocked but I still find it quite hard to light a highly reflective contoured surface to it's best (i.e without seeing squarish white patches from the emitters) and to show off the diamond to it's best (not have it look whited out). I think that a very large square box with mxi gradient emitters and some sort of dazzler might be the answer. Thanks for your push down that path!

Caryjames, I see in your screenshot that your front emitter is intersecting the ground plane. That might cause extra noise/longer render time.

[caryjames]

Thanks Bubbaloo- I know that I know better !

[oz42]

Blitzor - here are some quick (sl~10!) white studio shots with just the cyan LightBox (TM ) and Dazzler (TM ). I'll let you decide which is best



caryjames - The dazzler polys are merged into one object. I used a preset (200W hmi, I think?) but had to turn it down into single figures (~3) in MultiLight! Keep up the good work and let me know how the polar mxi emitter goes...

[Bubbaloo]

Top right render.

[GTJC460]

OZ42, Great looking renders! What kind of lighting are you using for the red planes and box?

[oz42]

GTJC460 - I can't exactly remember, it was a while ago, but they were just standard Maxwell hmi emitters - all I did was play with the wattage until it looked right!

[GTJC460]

Ok Thanks!

How do you keep track of all the emitter planes and know which one is which in the multilight control during the render?
