Short description of error
So I’ve been having this problem since working in 2.8 and I don’t have a clue what could be causing this issue but I went and stripped down a project as simple as possible trying to isolate the root cause. It seems its a mesh that has an emissive material and when I disconnect the node or hide the mesh the problem disappears. Weird thing is that the brighter version is when hiding mesh number 2. I am attaching the file.
You will see how the tone changes. This never happened to me after so many years using Blender until now already in a few projects in 2.8.
Exact steps for others to reproduce the error
- Open attached file.
- Render once using slot 1.
- Hide mesh 2 or disconnect the emissive node.
- Render again using slot 2.
- Toggle with J
Notice the different lighting between each result.
