dear manager i am univ student of south korea

i want to know how fastest rendering settings

and heres my setting value

It took a long time to rendering so i reduce my function value

this is when the computer is interpreting the rendering
i don't know why my gpu card using 5%~16%??

If it's the standard, wouldn't it be normal if it came out 100%?

I read the catalog because I was wondering what the problem was. '
I've got what I'm looking for yeah!!!


but there is nothing change function value tab...
could you help me this my problem

Hi Sang! Welcome here!! Is this the latest CentiLeo version? The latest package doesn't have the documentation you post here in a screenshot.
Also what is you GPU and what are your PC specs?
Can you send me this scene to for investigation and debugging? It's likely to be a bug there because CentiLeo usually utilizes the GPU for 97-99%

I found something unique while using it

if i used centileo IPR viewer gpu usage 20~30% and little bit faster than picture viewer rendering
but i need animation scene and export MP4 file

please help me this problem thank you

It looks like he has NVIDIA RTX A5000.
interesting GPU.
Do you have the latest driver, and is it a studio driver instead of the game ready driver?

I want to help to fix the issue. Pls, can you send me a scene to using some Google Drive or similar fileshare? There can be a stupid bug there

Thanks for scene! Downloading it now. I will get back once I test it
You can speedup the render by reducing the max iteration 1-2 and use denoise.
Just use ipr and check the iteration values, depending on the scene the bigger noise may clear around iteration value of 1.
I use 1-2 depending on the scene and with denoise always get reasonable result within a minute.
Unless your scene too complex to compute there is no use keeping higher iteration values. Just make sure static noise is turned on and use denoise.

Man, you have 48×2 core cpu running at 3ghz, then why gpu rendering?
physical render can render your scene within seconds if you setup the scene correctly.
If gi precomputing take too much time try qmc for both primary and secondary or turn off secondary.
even without gi turned on simple sky and ao setup can make your car look

Hi Sang! Thanks again for your scene! Sorry for veery long reply, I was too busy developing some renderer parts.
I have looked there and detected the reason of low performance. Basically everything is nice except of the emission material "LED_Beige". This material is assigned to selection of the building which forms a light shape around the building of the very irregular form. In fact the internal emission algorithm doesn't divide this shape too deep and hence doesn't result in the nice noise reduction. The other emission materials work fine in the scene: the emissive objects inside the building and the stree lights, etc.
The receipe to fix the issue:
1) Reduce the emission power of only "LED_Beige" to something less than 10 and make importance sampling Off. And you will see how the noise would be reduced a lot.
2) Manualy divide the selection of polygons that have assigned LED_Beige into multiple different objects of simpler shap.
3) Wait until I make #2 as an automatic internal process as part of more complex noise reduction algorithm. The main concern is memory but there are some ideas. Basically this process is implemented in the renderer core, but it doesn't divide to deep as is needed for such an object. So the further improvements are needed.
