For correct rendering of the caustics, you will have to use Bidir + Metropolis.
In this case, I believe you need PGI cache, as the caustics viewed from outside the water will be SDS paths. BiDir would help if the camera is inside the water.

Hi guys, this is an update for exterior scene. I need help to create a good water material for the pool; now is a simple plane with glass material IOR 1,333.I should to add interior or exterior volume? There is a lux tutorial? Here references https://www.archdaily.com/907558/gg-house-sommet

CoolColJ shared nice water material, it's still up in Indigo material database.
If my conversion is right from absorption to transmission (if transmission is color at depth).

Absorption:
Depth 1m
R 0.966298
G 0.985604
B 0.981817

Scattering:
R 0.985789
G 0.986962
B 0.98815
Scale 0.010038

From the data in refractiveindex.info webpage i calculate the
ior 1.3262
Dispersion 0.002152

Do not use multiscattering, it's too slow

I wonder where is the weird green/yellowish colorcast from sunlight coming.

I find luxcore sun incredible difficult to control especially without proper white balance controls in camera. The moment it goes closer to sunset/sunrise, the whole sun&sky system becomes pain. We need the ability to directly control sun color and in camera WB controls too.

Just use gain color :idea:

even desaturated sun color and even disconnected from sky model it will still turn weird yelowish cast when nearing sunset/rise angles. The only way around it is using direct light.

I've wrote a very very naive white balance plugin a while ago. I will clean it up, rebase and make a pull request so you can test it to see if that helps.

White balance in Photographer (addon) works nice with Lux.

My scene is lit with Hdri https://hdrihaven.com/hdri/?c=sunrise-s ... it_sunrise
I end up with this with the same HDRI : (Only gain color correction)
