Hi

I´ve a problem/question concerning the attached very basic scene, fire flies. I modeled a basic reflector in Cinema, size 10cm. I put a emitter in the center of the reflector and render the scene.
I don´t understand, why i have a lot of fireflies, white points around the bright zone . Without the reflector everything is ok.
I tested different geometries of the reflector, put the normals of the triangulated geo always to inside, changed the ground material with different values, changed
the environment Result is always the same, white points around the bright center of the light. The geo of the light emitter is a small sphere ( 8 ploys) or a single poly, same effect.

Why the white points ?

how about the reflector material?

Its a very basic one ... even with material or without , the effect is the same , white points. I also tried a very basic cube, one side open, normals inverted to inside, same effect ...
I´m a photographer and i want to model my different light formers to simulate a studio session , that´s the background for this ...


White values are all les than 225 ...

Hi Tom,

is the picture you are posting from the fire preview?
i see it a little in the preview here but when i render with your settings in production renderer there are no fireflies.

are you sure that your scene scale is correct?

Hi Daniel

Thanx, its solved now, based on your feedback .

I started the renderer directly out of Cinema, i activated def. "production mode" , but probably there is a bug ?!, not sure. If i start the renderer via Studio with activted production mode, everything is as expected "

Thanx´s !

Best,
Tom

good to hear!

i don't have cinema here, but i'd check back with the cinema section of the forum, could be that there is something wrong with the default values in the installer..
