Mesh won't react to light and remains bright I have an issue where some of my meshes won't react to light and just stay bright no matter what I do. I don't know how or when it happened, but I noticed it when opening the file.... This is in cycles render.

Edit: I only recently picked up blender so I'm a complete noob

Here are example screenshots of before and after:

What could cause this?
I somehow managed to enable ambient occlusion in the world properties, disabling it fixed the issue for me
