I have realized the white spots only appear when rendering within a region......I think this is something it was already mentioned.

It's shallow water on top of a glass structure.
I know it's a complex scene to calculate. I have tried with just the water, without any glass underneath and the issue stays the same.
It doesn't seem a material/object related issue.

thanks for your interest.

I have also tried to increase the numbe rof photons (from 5000 to 15000), didn't see any improvemnet. :(

General Discussion / caustics Issue
« on: 2019-08-02, 13:00:32 »
Hi all,
I am working on a scene that relies on caustics. I was hoping I could deal with corona caustics without doing major tricks or fake post-production.
The real caustics would come out ok, the issue is the number of white dots defining the caustics themselves.
Please have a look at there any way to improve the quality?
btw....this is a kind of 'noise' that won't go away with any denoise.

Thanks a lot.

Any workaround about using Phoenix Splashes with Corona? :)

Hi all,
hopefully this topic hasn't been already covered.
I know Foam is not currently supported by Corona.....does this apply to Splashes too?
I am trying to work in out, it seems the splashes shader doesn't behave properly though.

Thanks a lot.

kind regards,


I need help / Re: Architectural Foam, how to do it?

I agree.. No one here in the office likes the feeling of that sample.....but the architects are very keen on that! :(

Anyway, we are still trying hard.....we manage to work out the model for the far away shot...but the one for the close up no where near to be found.

thanks a lot again.


I need help / Architectural Foam, how to do it?
« on: 2018-04-13, 18:41:49 »
Hi all,
my client is asking me to find a way to show some panels (6 meters height) of architectural foam. I attached a photo of the given sample.

I thought the best solution would be to work with Corona Fractals but after a quick research, I fear it might be a quite slow and demanding solution.

I am happy to consider any creative solution.



I need help / Re: Volumetric pass behind glass
« on: 2018-03-15, 10:55:25 »
Thanks for your help. Luckily the camera is perpendicular to the windows, therefore, I have turned the refraction off and used the thin option.....all sorted now but it would be good to have the chance to make a surface invisible on a particular render pass.....

Thanks again!


I need help / Volumetric pass behind glass
« on: 2018-03-14, 13:59:38 »
Hi all,
I am working on an interior image with a big window (double glazing with thickness). Outside I have a a box for my fog.
I am trying to get the fog visible on my volumetric pass but the glass in front won't let me see it.....all black.
I have tried to make the glass not visible to masks...but this won't solve the problem. I would love to render the image just it possible?

Thanks a lot!
