E4 and E0 produce different lighting effects

Water I opened the defocusing , why not around to see it ?

I don't understand the question yet.

Turn on reflective caustics in the material editor (for the water).   e4 only.

The above diagram caustics are open, but still no effect .Do not know what the reason ?

[Roy Hirshkowitz]

Did you check Reflective Caustics in the material editor for the water material?  This only works with e4.

I don't think this matters-- but you certainly want the Highlight Intensity (on the page you've shown above) to be 1.0.  It might make a difference.

It should be working-- it's very hard to tell what the problem is without the model.  You can send me the model if it's practical.  Otherwise here are a few things to try (use a very simplified version of your model if possible):

• Make sure a lot of direct sunlight is hitting the water surface-- caustics work better with intense focused light.  
• Change the sunlight angle around-- make the sun high in the sky.  
• Try turning off the skylight using lighting channels and just using the direct sunlight portion.  The image will not be good, but you may be able to tell if the caustics are present.  
• Try making the water material out of opaque chrome to see if more reflection is needed.  That may offer a clue.
• Try a different pattern on the water surface, such as Pyramid-- to see if you get more caustics.

Roy Hirshkowitz, thank you , I upload my model to you .
