Caustic problem

[martinopheim]

Hi,

 

Having some issues with rendering the caustics effects in my scene. I end up getting all these spots, which I can't get rid of and it just looks really wierd. It seems to be the same thing that is causeing it from the water in the tank to the right and the error just reflects off on the walls and stuff.

Tried turning up the caustic subdivs on the light to see if it helped, but anything over 2500 and 3ds max crashes during rendering, after the "Building caustic photon map" phase. Also doubled the global Subdiv count in the render options, which didn't make 3ds max crash. Any tips to what I am doing wrong would be very much appreciated.
