Bidir - problem with visibility caustics

[jjaz82]

hi Ondra.. it's normal this shadow without caustics?
illumination by a corona light, type rectangle, intensity 50000, dimensions 80 x 70 cm

[Ondra]

i dont know the scene configuration, but never use bidir with hybrid glass, I havent tested it, and it is not needed.

[jjaz82]

sorry, the file name it's wrong.. in this scene i didn't use hybrid glass..

this is an other test.. looks perfect.. :)

Good afternoon.

tell me how this scene


achieve caustics on the ceiling and walls?
thanks in advance.

[SLOM]

how to get rid of the noise in the caustic?
to render not so long gone
it is possible as it is in a separate layer to render it?

[Ondra]

Did you increase max sample intensity value?

[Utroll]

if it's a whole sea that we may see outside thru left windows, you could may be fake it as well, don't know how it's made but in worst scenario it's a cpu killer :)

[SLOM]

Did you increase max sample intensity value?

if you know that? I did not understand what this parameter influences?


that he was 20 that the difference nezametil 9999

left outside the windows is not the ocean flooring :)


the pool water is just a plane with noise
tried it yet volumetric water, the result is almost the same

This is interesting, I'm trying to make caustics in a swimming pool and nothing worked so far.
The water is a single plane with noise and turbosmotth.
Water is refractive and has caustics enabled. Illumination is by corona sun.
The rest are default settings. What am I missing here?
