One of the image is CPU render (2 CPU workstation with xeons on board) and second is GPU (nVidia Quadro M6000 24GB)
This is GPU
This is CPU
I don’t know why is such difference between this shots
Hey Cezary,
This looks like something we should investigate.
Please make sure your Keyshot and GPU driver are up to date.
If that does not resolve the issue, I would suggest you file an issue with the support team.
You can create an issue here: https://help.keyshot.com/support/home
Hello, maybe if you can share this scene, so we can open it and see what’s going on. When you are in the GPU rendering mode, and you hide that glass, how it looks? Its just the glass which is not working right or its the material behind that glass not working? I believe the material behind that glass is not working in GPU mode. are these small dots emissive material?
As Niko stated updating the GPU drivers to the latest would be the first step.
You can find your specific drivers here: https://www.nvidia.com/download/index.aspx
and sharing the KSP for us to trouble shoot would be the next step.
Sharing it through WeTransfer is the best and safest way.
First of all i am using Keyshot in work so i am limited to check something only at office.
Second - this is outdated gfx (Maxwell technology and nvidia not supporting this card anymore)
i have latest (for this card) drivers. and last but not less important - keyshot 10.2.
Maybe all of this points makes some problems.
@TextureMan, yes, there is a glass panel and behind is emmisive material with gobo mask (illustrator file). Your suggestion are correct - i found an issue - double glass in one place, when i removed on “layer” on GPU now is everything ok

Nice job, mate 
render looks good, but to be honest, I am curious what is it it’s some kind of detector or something similar?

Sounds like the issue could be the number of ray bounces too. If you turn the glass back on (both layers) and increase ray bounces, I wonder if it will become transparent. Perhaps no matter how many ray bounces, the double glass will remain black. Glad you figured a solution!

This is digital instrument (speedometer with many other indicators).
Since i have access to keyshot and solidworks i started design of many elements as digital library for my future (maybe even paid) job as motorcycle designer (mostly custom for clients) so this is very good way to grind own skills.
i think that next render will be as shown on picture with details, maybe i will try some animation (but i think that my workstation is too old for this).

This last render looks really good. Nice job I really like the design of it. It would be nice to see even simple animation of this in the future
no no, this is real photo of product which is not my design. Only renders in first post are mine. I have model of this unit because i ve designed custom mount on bike (triple clamps) and few others addons to make this bike unique.

My Bad But it still looks good I was little bit confused cause your render looks exactly same like that real life product
