x Light Paths (default setting)
Add Light Tracing (default setting)
Clamping : max Brightness: 0.70 (value suggested)
x LuxCoreDenoiser OIDN - 6000
x LuxCore Halt conditions 150 samples
x LuxCore Caches:
x PhtonGI Cache (default setting)
x Environnement Light Cache (default setting)
x Direct Light Sampling Cache (default setting)
Like you have a lot of performance left.

For this scene you don't need Light tracing (don't see any caustic) but it is for the windows glass panel just make shader glass shadow color to 98% white.

for photon Gi you can boost performance by reducing the brute force radius scale from 8 to 2 or 1.( this will allow for mor surface to be treat by the light cache vs brute force. higher value egal more brute force more accuracy so reduce until you get light leak or error light that)

BYOB, Sharlybg, Thanks for your feedback and way of improvements.

At first, I try without Direct Light Sampling cache => render time is 5:05:85

At second, I try:
- without add light tracing
- 98% white shadow color for glass shader
- PhotonGI Cache with Photon Depth = 3 (vs 8). Is not possible for me to choose 2 or 1, 3 is the limit min of the value.

The result is good with less noisy, the render time is 5:26:41.

Thanks

I think you have confused photon depth with brute force radius scale.

Sure !

they are both at 8 by default but the one you should change to 1 or 2 is Brute force radius scale ( this one have a major impact on performance). So leave photon deph at 8.

Yes,

With Brute Force Radius Scale 8 to 2 : Result is good with less noisy than original, Render Time is 5:07:08

With Brute Force Radius Scale 2 to 1 : Result is good with less noisy than original, Render Time is 5:08:67 (same quality compare with value 2)

With Photon Count (Millions) 10 to 3, Result is good (noisy), time render is 04:44:55.

I appreciate your videos.
Also, If you make videos in French, I would be happy to follow them to fully understand the engine parameters.
The light with LuxCoreRender is awesome.

Have a good day and Thanks for your help.
