I am working on a scene in blender related to Minecraft but for some reason my render image have small yellow and red spots sprinkled which are barely noticeable , is their a way to fix it. it might be a problem with cycles as it works fine with eevee.
These are often referred to as "fireflies," and they're a common artifact in Cycles renders. Because Cycles is a path tracing engine which uses pseudo-randomness, some samples will find light sources and illuminate pixels that would otherwise be fairly dim.
You can either increase your number of samples (although it may take a very large number and long render time to eliminate them entirely), or you can take a look at Blender's relatively new built-in denoising options.
