I am trying to create a stage in the Cycles renderer. I have modeled a stage light that looks like this. It has a circle with the emission shader to act as a light source

Stage Light

However, when I try to render the scene, speckles appear on the stage:

Sampling

As you can probably tell, the more samples, the more dots, but they become smaller. Given that it took a couple minutes to render with 1024 samples, I don't simply want to set the samples to something ridiculously high like 16,000. Does anyone know what's going on?

(The Wooden Floor uses the default Diffuse BSDF Shader with an input from an Image Texture, mapped by a UV texture coordinate. I would put an image but I can't upload any more)

  • enable multiple importance. See : http://blender.stackexchange.com/questions/8152/what-is-multiple-importance-sample-option and: http://blender.stackexchange.com/questions/5309/when-should-mis-be-used-and-when-should-it-be-disabled –  Jan 12 '16 at 23:31

  • Can you uoload your file? Please pack your texture image into the file and upload it to http://blend-exchange.giantcowfilms.com/ , then edit the resulting link into the question. –  Jan 13 '16 at 01:05

  • I enabled multiple importance and there are still speckles. I think they're called fireflies. – AMACB Jan 13 '16 at 01:31

I figured out the problem: I needed to turn up "Clamp Indirect." The Article Here has a bunch of solutions, and the only one that worked for me was the 6th option.
