After creating an animation, I decided to try and optimize my render settings so I could get the final result much faster. (I am using cycles) A lot of people advised me to lower the bounce count, so I did just that. In order to make sure I wasn't losing detail, I decided to run test renders with various bounce counts.
During this testing, I encountered something strange.
Inside my scene, I have a somewhat shiny object with low roughness (Principled BSDF, nothing else). I also have an object with an emission shader. When rendered, you can see the reflection of the emissive object in the shiny one. However, when I set the bounce count to 0, this reflection is still visible, even though it should not be because, well, its a reflection and 0 bounces should mean there are no reflections and the scene would just be shrouded in complete darkness unless the ray hits a light source.
Why is that so?
Unfortunately, I cannot share any images because I have saved them in OpenEXR format.
