Hi all,
If I were to render a scene which at the beginning produced lots of fireflies does it mean that if I rendered it for an infinite amount of time at the end there would be no fireflies left?
I do interior scenes usually and fireflies are my biggest concern. I just don't see the point of the fireflies removal tool since it leads to degradation in quality.

Even with PT and PMC I still get these annoying fireflies.

Thanks guys.

There are many things you can do about fireflies. One more time: do not abuse the roughness parameter on reflective or refractive objects; direct light (sun) as well as other powerful light souces will produce fireflies due to the strong caustics; do renders 2,3 or 4 times bigger in resolution if able, and scale down in photoshop; do a few renders to scramble the samples, and composite them in Photoshop; remove the fireflies manually in photoshop with a 1 pixel brush; pathtracing does produce more fireflies than pmc, whether direct lighting shouldn't produce any; turn the maxdepth to a minimum, usually 8 or even less is enough.

Do you have fireflies if you use directlighting? If so, if you have glossy materials in the scene with the roughness set to the minimum, you can increase the roughness of these a bit.

Thanks you guys, will try your tips tomorrow morning.
All the best.
