So built static lights are not working when I play the game. Here are my details:

- Nanite Disabled
- Lumen Disabled (using None for GI)
- Virtualized Textures enabled
- Virtualized Textures for Lightmaps enabled
- Force No Pre-Compute Light is disabled
- Lightmaps are all good (no overlap or wrapping)
- Only point lights, all set to static (about 40 of them)
- Several Reflection Captures

I’ve tried with both **Build Lights** and GPU Lightmass.  
When I build lighting, it actually does work and I can see the new lighting in my scene which is clearly different than dynamic GI, it just all goes away when I actually play in PIE.  
Even stranger is that when I package the game, the baked lights do work, so its a pie / standalone only problem??!  
This seems like a bug to be honest since it works in packaged, does anyone have any ideas?

You need to enable the following option (this will require a restart):  
Project Settings-\>Engine-\>Rendering-\>Allow Static Lighting.

Yes sorry, I did not add this to my bullet points but I already have static lighting allowed.

Well, if it only disappears in PIE, then it most likely is a bug. Feel free to report it at [https://unrealbugsubmissions.epicgames.com](https://unrealbugsubmissions.epicgames.com).
