Help with caustics !

[rmejia]

How can I make the water caustics sharper, like in this pool:
http://www.chaosgroup.com/forums/vbu...ad.php?t=41081

I have tried a million things and cant get it like that. The caustics numbers are:
Multiplier: 1
Search dist: 4"
Max Photons: 60
Max density: 0

Any help would be greatly appreciated, thanks.

a simple thing that you can do is use fake caustics,

http://www.lysator.liu.se/~kand/caustics/

that program makes some caustics maps. saves allot of rendertime also

[vlado]

You can try to reduce your caustics Search radius and maybe add more caustics subdivs for the sun. Also, to save some memory, you can try setting the max. density to something like 0.5''

Looks more interesting , it seems to be caused by the bump map mostly ? With calmer water it would probably not show so much ?

Here are some examples I was trying to use as reference:

I suggest you to make water plane with more subdivision (simple plane) and add noise modifier too...
Like you said it's hard to get nice caustics with calm water

[rmejia]

I give up



Another test:

Hmm... what Visuemporec did looked pretty good. I would try whatever settings he used.. and maybe less displacement/bump on the water plane.

I would too ... but I have no idea what the settings he uses are !

[MikeHampton]

Ask him for the file back? He probably didn't offer because it sounded like you liked it better but still wasn't exactly what you were looking for. At least that's the way I read your response.
