Can someone help me to optimize the scene in Luxcore as in the picture ?
I've been reading in the forum for hours, but my language skills are not enough!
My failed attempt
The LuxCore render shows realistic caustics.
I don't know MentalRay but it seems there you can adjust caustic brightness.
In their image the caustics are totally overblown, look at the white half-moon under the rim, that's light shining through glass only (not liquid) on the ground, it should have the same brightness as directly illuminated ground, not more.
You can get it a little more pronounced by disabling world background light (HDRI).
