Sharing one of my Cyberpunk Vehicle concept design.
Using very simple basic lighting setup in Keyshot for visual study before porting to game engine.
Render with GPU mode and 20K samples.
This is awesome! Thanks for sharing these. You might find 20k samples to be a bit high - but if you’re OK with the render time - it’s a minor detail.
I think you will like these webinars / quick-tips. The lighting effects may not transfer over if you’re exporting as FBX into a different software - but it will really help take your still images to the next level. I think dialing in the physical / emissive lights and the environment lighting will make a world of difference. There are some shorter videos as well as a comprehensive series on automotive rendering.

Thank you for the info sharing.
Yeah, i was using the Keyshot as basic visual guide study.
The game engine will have their own physic / light system.
The reason why i use 20K samples in GPU mode is i encounter low / bad quality result before. I still learning the curve of Keyshot GPU render.
CPU vs GPU render samples is kinda different.
Below is some sample i can share during the case study. (I m using RTX3080)
All these render are 4k resolution except the first 2.
CPU 100 Samples (as can see the wall did not cast the reflection in CPU render compare the bottom GPU render)
GPU 500 Samples (Reflection on the wall is on)
CPU 200 Samples 4 hours
GPU 200 Samples 10 minutes
GPU 4000 Samples 3 hours (still can spot noise at the back alley and some undetailed stuff)
GPU 30 OOO Samples 6 hours
GPU 200 samples vs GPU 4000 samples and above, instant can spot certain ray / light is much better on higher number. Number do play some role in GPU render mode.
When scene / product has few / too much light source or reflection, GPU render seem do a pretty good job.
Also using GPU render could enhanced the light ray on certain material / reflection. The image is more brighter too compare CPU render.
This is just my 2 cents opinion only after done some study.
Those results don’t lie! 6 hours is reasonable for 30,000 samples. I think my brain did the calculation for a CPU render @ 30k samples which would be brutal.
