Blender dark pixel artifacts while rendering - How can i solve this?
node
Hey
I've been recently trying to render an animation, but i have an issue with the light. Here is th eproblem.
As you can see those pixels are horrible and shouldn't be there.
Here are some info about my project:
-There is only one light
-All render options are set to default
-I tried upscaling the samples, but that didnt seem to work
-I've tried to render other scenes with the same light before this, but this is the only scene that gives me problems
-The objects are simple cilinders, there is no non-manifold geometry or something like that.
What do you think causes those visual artifact?
Thanks in advance for your answers.

Eevee or Cycles? I guess with animation you use Eevee. Try increasing the shadowmap size. Are the lights baked?
I unfortunately haven't rendered with Cycles for a long time. Lots has changed since then. Does Cycles even have square sample settings still? But try to clamp the light, and go crazy with the samples. And play around with the bounces too. Emissive lights needs lots of samples.
Another thought is that the denoiser is having fun here. Try without. Then you might also see all the fireflies.
Here is the result.
Still weird though. As i said i used this same light for other similar scenes and nothing like this has ever happened.
Here is a previous example.
Thank you again for you time
