So I’ve set up an interior scene. I have a directional light in the scene, but I’ve set it so that it doesn’t effect anything in the scene, I’ve Put a lightmass importance volume in the scene, I’ve adjusted the global post processing auto exposure, but I’m still getting a blown out floor. I’ve tried it with a static mesh, and a BSP. What hapens is that at least with the BSP i’m getting cast shadows on the floor like I’m supposed to but if I click anything in the editor, to move, click on to select an object, anything. the lighting is blown out again. ![43910-good.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/1/0/5/105c21a0025c5d248a7904af906bdc4a19891b70.jpeg) ![43911-bad.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/4/9/7/497534d1f83b64ee66a209e2becb2d436f7f5e29.jpeg) I’m not sure what to do. If anyone has any ideas or suggestions on what might be wrong, I would appreciate the help! ---

Every time you move an object in editor it loses its lighting data and the lighting will have to be recalculated.
