Underwater caustics look like pixie dust (Max 2010)

[Caz2005]

Hi there,

I'm trying to create a scene where the camera is in shallow water. All it going well apart from the caustics.

I've gone through a bout 5 tutorials on this but the only result I ever get is tiny little speckles that dance around the scene.

Through getting fed up and just trying to see if I get lucky I've mucked around with the settings, but I always get either a really bright scene, a really dark scene or really bright fairy dust, lol!

Here's a screen grap of a render with settings....



Any help would be greatly appreciated, many thanks in advance.

Oh, here's some scene details. I'm using the watersurface archmat with generate caustics enabled. The only other scene object which generates is my Daylight system. Everything else just receives.

my first thoughts.. are what are your material setting... or have your objects been set to recieve and reflect..

next thought is.. what are the scales of your models.. as your radius setting could still be too low..

Hi there,

Thanks for replying. You know, just before reading your reply I was looking at the lume shader and thought that the default wave sizes looked a bit too small for the size of my scene. Tweaking them has really helped a lot.

Just now trying to backtrack and re-learn what else I've done mucking around with the caustic settings. I'm getting there!

Thanks again for replying!
