Breguet Reine de Naples - Luxury watch render & question

[Neo]

hi there! i'm marco, new here, hope you like my render! i modelled this famous Breguet on rhino, you like it? any tips to improve the render?

Also i have a question for you: this image taked over 7 hours rendering...it's not too much? i hoped keyshot was a little more faster.. i attach the
render setting for this one... i render in a 2012 Macbook Pro 15"(i7 3720QM 2.6GHz , 1gb dedicated Nvidia grapichs and 8GB RAM)it's a normal render time
for you with this specifications? Thanks!!

Great render for a new user - well done.

Regarding render times. KeyShot gives you three choices. Max Time and Max Samples which is pretty much the same engine that is used to preview your scene when applying materials. Then there is the none realtime renderer or Advanced Render (slowest). The advanced is more accurate but lacks the ability to do things like Interior Mode render. Your scene has a lot of gems in there and they will require lots of cycles to calculate at render time, so you would need lots of cores/threads to speed that up. Your processor has 8 threads in total and the processor speed is not that great.

A nice trick for you would be to use Interior Mode lighting (KS6 required), and then to use max time instead of the advanced renderer. If you press H when KS has your scene loaded you will see the Heads Up Display that will show you the time and speed the render engine is calculating at, you can use this as a guide to set your max time to.

thank you very much for the advice...i used advanced option because i wanted use and lock my custom lighting presets( ray bounce, indirect bounces, shadow quality ecc)and I didn't change them.. if i choose "maximum time" this setting will change right? yeah probably i will use max time instead the advanced time, i can't waiting 7 hours each time... hoping that there is not much difference in the final result between the two.
And which is the difference between max samples and max time? max samples is more accurate?
Thanks again
Marco

My understanding is that the Advanced Render ignores the lighting presets, bounces etc and enables you to set your own. Also the Max Samples and Max Time are progressive render types, that is you can see if image improve as you watch it progress. The Advanced Render is a non progressive renderer and you will only see one bucket per thread rendering at a time. Advanced is more accurate but can not do things like Interior mode lighting and (not sure on this in v6)  motion blur etc.

Where the progressive renders suffer is that you cant set antialiasing or the quality of the depth of field or the quality of caustics. Otherwise they are pretty much identical to the advanced renderer, they just need time to get there. Most people find that they can reach a good quality image in the Max Time or Max Samples render mode much quicker than the Advanced Renderer

Have a play, you can't hurt anything and see which way works best for you

IMHO you turn off the caustics, that should reduce the render time. In live render mode you'll see the results, when you reduce the ray bounces. Perhaps a value of 10 is enough (I guess), 'cause the gem stones are very tiny. And maybe you used the NURBS mode?
You will find your balance between render time and quality with a lil practice.

Good render so far!

really thank you for the explanation, now i understand the difference between this three  way. 
So i'll try with max samples/time mode ( as I understand that are identical in terms of quality) and playing with setting..I will keep you updated!

thanks! so for you if i turn off the caustics i'll have a pretty identical results? i'll try that ....for the ray bounces i used a lighting preset of keyshot(jewelry preset already exist), besides i'll do a more zoomed render focused on gems, so i think i'll keep this settings on 24...
Yes, i used the NURBS mode, cause i find that if i zoom on the model i can see too much the segment, so i keep always active...

Thank you all, i'll post new render soon

Hello, just stopping by the say that it's an amazing render :-)
No matter the render settings, it's well worth an overnight render ;-)

[LayC42]

ok, that explains a lot. So pls let us know how fast KeyShot renders the watch in polygon mode with reduced ray bounces calculated in max sample mode (the head up display will show some values).
Maybe you can share the result.

Really thank you man!  I appreciate it! that means i'm working in a right way!

Hey Marco, welcome. This looks fabulous. I would certainly drop the ray bounces and try interior lighting mode. I'm not noticing any caustics, so you may want to try one with that off as well. Looking forward to seeing more!

Hey guys, i'm back, sorry for the lack but i was very busy these days. Here new render, this time i used the "max samples" render way(whit a value of 400) and interior mode...the final time it amounted about 2 hours...i think it's a good compromise, don't you? 

[TpwUK]

2 hours is much better than 7
The result is acceptable - Well to me it is. It's more important for you to be happy with the result though
