Very nice work, thank you! I rendered the scene and this is how it came out. I put in the ies file and rendered in PT not sure why it is so much lighter than yours?eyeonestudio wrote:Real World Light Have Very Complex Falloff. Default Area Light is Not.
If you want Real Light Simulation... You Need that LED "ies" Data File.
You can use with octane ies light.
DL4 use Pathtracing Kernel
Firefly --> Reduce GI-Clamp Value
Glow --> Use Post Processing : Bloom Power If you want volume light... do not use pmc. very painful.![]()
serch this forum. keyword "volume light".

Thanks, I will give it a shot. Any suggestions on PT settings?inlifethrill wrote:I hear you, however "spreading more light across the wheel which is more true to life" is not a feature of PMC or of any other kernel for that matter. It's about using the proper settings, not Render Kernel. There are very few cases where you will be forced to go with PMC instead of the faster Path Tracing or Direct Lighting.. and this is not one of them. Spend some time with Path Tracing, i bet you will get where you are headed in far less time.buzby wrote:I was saying aboveinlifethrill wrote:Why would you even use PMC for that? By the look of it - Path Tracing or even Direct Lighting would be enough to render this in a blaze.
I was using PMC because I noticed it handles light better, seems to spread more light across the wheels which is more true to life like the real product we are displaying. Also I thought I read that there are less hotpixles with PMC

He is using black environment color.
Another fake try here. Propably your modelling/setup does not match the real model. Somethings is blocking the lights to reach to out.

Another beauty, love the metal texture, thank you for the scene redo aoktar!aoktar wrote:He is using black environment color.

BTW you are rendering at 32.311 I am rendering at 5.7 is your signature still your current setup? We both have a titan You are getting that much more with 2 590? I have a couple 580 lying around, I may have to put them back in. The 590 were too hot with just air cooling

I'm not using texture environment.
1. No texture environment. use one area light
2. setting --> Other --> default environment color (Black)

Thank you all for the help, I completely overlooked using EIS lighting, for some reason was not associating EIS lighting for LEDs
Also thanks for the PT suggestions have reduced my renders from 6 hours to 30 minutes with decent results.
I need to update my hardware so bought a couple 970s last night to get the render times more practical for our workflow. Then I read about the 3.5 memory debacle, anyone know if this is effecting Octane? I read through the forum but nothing jumped out with folks being disappointed here with the 970?

The '900 series talk' has been pretty widely covered. Luckily we've faced significant improvement of 900 series. Grimm reported here

980 is close to 780 so it is not that bad. It should draw less power (about 40-50W less than GTX 780 in Octane, but under heavy load the power savings may not be that significant).
What I could recommend - choose your card with respect to vram amount you need and budget
- If 3GB if fine 780Ti is a winner. Even 780 3GB is a great choice, not to mention - 580 3GB is still a great performer.
- If 4GB is what suits your needs go with 970 which is close to 980.
- If 6GB is a must - 780 6GB is the best you can get for money - but unluckily so hard to get these days. Then Titan (Black) - search for used pieces. And if you want to have 2 gpus titan Z for about 1500$ gives you power of 2xBlacks.
Shortly speaking - if you can get 6GB used cards like titan (black) for about 500-600$ just get it.
