You used this mode in the "sphere" example, right? I can only recommend increasing the step size as much as possible and enabling "single bounce only".

This should now work better than before. If you render a region, this should not result in glitches/splotches, but under the hood caustics are calculated for the whole image, so there won't be as much speed up as expected.

Throwing one more. :)

This scene looks so awesome. Can you share it how you did this? I have never used caustsics till today - because it was not needed for my daily work.

Greetings Hannes

maru:
Here is my scene.

A couple more comments:

Tested on a simple scene with a rectangular pool, water is a box with tessellation and a noise modifier on the upper polygon. Default Sun & Sky. Materials without displacement.

1) If I submerge the camera under water and turn OFF the "caustics in volumes" checkbox in the render setup, the caustics at the bottom of the pool are calculated incorrectly, turning from correct patterns into mush.

2)And I also noticed (I think I haven't noticed this before) that when the camera is half submerged and the Camera Physical Size option is turned on, this box casts a shadow and prevent caustics from appearing, which in my opinion isn't correct.

Hi Marchik, could you share this scene? (via PM/support portal/directly on the forum)

Thanks for the response, maru, of course! I edited the scene in such a way that 2 problems became immediately visible.
