So i followed a blender guru tutorial about lightbulbs. I got some noise in the render and don´t know why, cause i did everything as told in the tutorial. What can i do (except photoshop it away)?

  • $\begingroup$ Have you tried filtering glossy? It's under Light Paths on the render panel. $\endgroup$

  • $\begingroup$ i tried filtering glossy. the only difference is that the glowing bulb looks different. $\endgroup$ Apr 26, 2017 at 14:30
  • $\begingroup$ You could try a filter of 1, but it appears to me that those white spots are not noise (specifically) but in fact reflections of that one point of light in your scene (or other lights, if you have any). So there's really no way to eliminate those, except for making them look better by rendering with more samples. Also, you could see this post for many more tips on reducing "fireflies": blender.stackexchange.com/a/30465/16835 $\endgroup$

  • $\begingroup$ Another note to my above comment, it may really help to try disabling reflective and refractive caustics under Light Paths on the Render panel, as is mentioned in the post I linked to above. $\endgroup$
