Dear blender community,

So I'm pretty new to blender and general 3d creation and now I rendered my first good project but It has many point where the pixels doesn't belong to or the color of them isn't matching. I can provide a picture for that too. Would be greate if someone could help me. I can provide any additional information if needed. You can see the pixels mostly on the table and at the plant. I could remove some of them when I added another light that directly lights in the room but I don't really want that to be there because the picture is too bright then. Thanks for helping!

Lighting i used

  • Yes, sure I'm new to this community here, thanks for the info I'll change that in some minutes. Need to render that again✌ – sxck1337 Apr 21 '20 at 12:08
  • hey, no this didnt help much, but thank you! i'm happy over every thing that could help. I'm also trying to fix it myself, maybe i finde the right settings :) – sxck1337 Apr 21 '20 at 13:00
  • The settings of the linked question will solve it (there is nothing more to say), you just have to read it. In short: I suggest to bump up the samples to at least 1000, use a better image texture for the floor and only use the denoiser in the compositor: https://blender.stackexchange.com/questions/173760/how-to-properly-connect-the-denoise-node-in-compositor/173761#173761 – brockmann Apr 21 '20 at 13:21
  • Okay thanks, I already use 1000 samples, I'll make some better textures. Thanks for your help – sxck1337 Apr 21 '20 at 17:30

From what I see and understand from your description, you are seeing something pretty common when using the Cycles renderer: Noise. (The bright pixels are sometimes referred to as "fireflies")

There are several ways of reducing this effect: 1) Try a higher sample count in the "render" setting Samples setting

2) Use one of the denoise options, for example this one: Denoise

3) Switch to Eevee Render Engine: Eevee

I tried the evee render that looks pretty good but it isnt rendering my backlight material for cycles renderer. maybe you cloud tell me what i need to change in denoising to make increase it. just the strentgh? and im using 1000 as my rendersample but isnt really getting better. i appreciate your greate help! – sxck1337 Apr 21 '20 at 12:51
