Hello there!

I placed several fixtures outside the building, and they initially appeared and worked as expected. However, after moving some objects, removing other indoor lighting, and recalculating, the outdoor fixtures no longer seem to work.

I referred to a similar question in this forum and checked the light scenes. They don’t appear to be the issue. I also ensured there is a site/floor, and the lights were working properly. Despite this, the fixtures are not functioning as expected after the latest calculation.

I've attached the project files for your reference. You can see that in one version (during the process), the lighting is working, while in the final calculation, it's not.

Looking forward to your advice!
