David, as always, beautiful work! It really great seeing such amazing HDRI's light a scene.

thx a lot Ted

Very nice. Did you use caustic for water?

As Roju - I really want to know how you got the caustics in the water,

The following tips have been shared by Shiyan lin , and it may help you:

1.Do remember to turn off "affect shadow" option in refraction roll out
2.Don't use bump to deform your water(let's say it is just a simple plane),instead use displacement.
3.Use NoiseB texture,and try different type of noise,turn on interactive rendering and tweak these settings,find the best one suit your need(or you can use a texture as you wish)
4.HDRI can not produce vrey nice photon map,instead use a direct light like Vraysun.
5.You can tweak photon emit radius in VraySun to control the area of caustic effect.
6.You can tweak multiplier in Caustics rollout to stimulate caustic effect.

This strategy still isn't working for me...

What value did you input in the emit radius?
