I'm a beginner in Blender and I'm trying to render a scene using Blender 2.8.

Unfortunately the result shows strong pixelation. As far as I learned for version 2.7 (Cycles) you have to use a denoise function as described here.

But I don't find a function like this for EEVEE. I have tried to use a higher number of samples. this also improves the result. But these coarse light pixels remain. Does there exist a function or method I missed to reduce pixelation?

Indeed there are no denoise options in Blender Eevee for now.

What you can do instead is playing with the filter size, which can be found here:

Little demo of how it works: filter size demo

Just do some tests and see what works better on your case. Each render is different.

Alternatively, you can use the D-noise addon which will allow you to use denoising on anything using Blender's Compositor.

  • $\begingroup$ Thanks L0Lock, that was a great suggestion! Filter size can remove some of the large white noise, but it does blur the image a bit, hence, experimentation is needed. D-Noise does a good job of removing low-level noise in EEVEE, although it doesn't automatically launch itself after rendering in the experimental builds of 2.8 (only in the official 2.8 build). :-) $\endgroup$ – Copperplate Sep 4 at 20:32
  • $\begingroup$ Also increasing filter size can have performance benefits. For example, at 128 samples, an HD render dropped from 128 seconds to 96 seconds by increasing filter size to 1.75 pixels (from the 1.50 default size). $\endgroup$ – Copperplate Sep 4 at 20:38
