White particles appear in renderings.

Hello,

I’m new to Blender and have been learning via Youtube tutorials. Can anyone tell me why white particles keep appearing in my renderings? I tried turning the samplings up, all the way to 3000 and they keep popping up everywhere. Please see the attached images. Thank you!



Hi,

those are called fireflies, you can do a variety of things to prevent them from popping up, like using clamping, disabling refractive caustics (for a diamond render like the one you show you’re better off using luxrender anyway I think), using branched path tracing and bumping up the glossy/refraction samples, etc.
