Hello everyone, Im a bit new to unreal engine 4 but I’m getting the hang of it.  
but today I’m having a strange issue. so here it is:  
I was working on an appartment scene and everything was going well until I rebuild the lighting, because after that my shadows looked like this:

 ![70848-ue4editor+2015-12-16+16-00-50-15.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/d/1/5/d15100eddda2da9fdb724c6d53f109b5efcb27b9.jpeg)

I don’t know if this actually is an issue or if it’s just the engine not detailing the shadows to much because it’s just a preview.

Hi Cornelis,

When using precomputed (baked) lighting there may be instances where you need to adjust the lightmap resolution of the mesh receiving the shadow. This will help the baked lighting/shadow information to appear with more detail.
