I put three doors in my project, all sharing the same BP and using movable mesh. However they are not under same brightness in level map. As you can see in below screenshot, the left one is darker and the right two are brighter, which are not supposed to be.
If I drag the left one to right, it’ll also become brighter, but the static meshes I put in the same place will still be dark as usual. I’ve tried to rebuild light but that doesn’t work.
And following is a screenshot under light only mode for your reference.
