Living room. Dots problem

[irrreal]

Hello!

Corona is just awesome.
But sometimes I get these strange dots.
How can it be fixed?
It does not depend on render time

Can you post screenshot of your settings?

[irrreal]

I will be able to make screenshot tomorrow if necessary.
But it's all by default. Lights are corona's ies, environment - coronaSky.
Scene was created in "slower version" of Corona but rendered in full-speed i7 CPU. Could it be a problem?

[Ondra]

no, the two versions are identical in shading

[maru]

I would suspect these fireflies come from the ceiling lights. It could be caused by:
a) IES lights
b) light bulb object/material in wrong place - do not use refractive glass
c) object/material of the light socket, mirror-like material reflecting light could cause this, refractive caustics could cause this

Try to use other Global Illumination for reflect/refract materials with CoronaRaySwitch Material.

Does the wall material have a bump map? If it does, what is your map filtering settings and what is the bump mapping strength?

[irrreal]

thank you for all advices.
The best result that I got in this scene was after setting lights from IES to disk.
But still it wasn't ideal.

I think the scene is somehow corrupt, so will see how it gonna be in further projects
