Hey, so I just rendered this Teapot, and there are these white dots.
Why are they there and how can I remove them?
“Fireflies” can happen in scenes with many reflective or refractive surfaces (glass/mirror). Here is a Blender stackexchange page about it. Here’s an article with possible solutions you could try: https://www.blenderguru.com/articles/7-ways-get-rid-fireflies
If you’re not rendering a test render, don’t just throw a denoise filter on it. Better solve the problem than hiding it. Denoising is fast and creates good results, but still removes details. So when you add textures to your scene, this might already cause problems.
