To mitigate this, start by optimizing your lighting setup. Using more lighting sources or adjusting their intensity can reduce the need for high ISO levels, which are a common culprit for noise. For instance, indirect lighting techniques like ambience occlusion can help distribute light more evenly. Another effective method is to increase your render resolution. Higher resolution captures more detail, which can inherently reduce noise. Additionally, employing anti-aliasing techniques, such as MSAA (Multi-Sample Anti-Aliasing) or SSAO (Screen Space Ambient Occlusion), can smooth out edges and reduce noise, providing a clearer image. For 3D render artists using software like Blender, settings such as the number of samples per pixel can dramatically affect render quality. Increasing the sample count can substantially reduce noise, though it will also increase render times. Therefore, balancing sample count and render time to find an acceptable trade-off is crucial.
What is the difference between Eevee and Cycles renderers in Blender?
