How do I remove glowy graphics anomalies from my level?

Hello,

I am a new Unreal user. As I built my level out I started getting these glowy anomalies, even after building lighting in my scene. See the screenshot here, and note that some things are glowing red and others green/white. It’s different every time.

Now, if I go to Quick Settings > Engine Scalability Settings and turn it down to Low, and then back to Ultra, the problem goes away as the scene re-lights itself… usually. Or, one object will stop glowing and another one somewhere else will start up. It is very inconsistent. Usually it is worse after building lighting, and then generally better after I have reset the Scalability settings as described.

I make a habit of creating lightmap UV sets for every object.
Using Unreal 4.4.3 (upgrading to 4.6 dogged my framerate significantly)
Geforce GTX 560
8GB RAM
This does not occur when I load the demo projects. That leads me to believe it is a performance issue related to the assets in my scene, but if so, I don’t know the culprit.

Thanks very much in advance!

Hi Danodin -

When you reset the Engine Scalability settings that will invalidate the Light Build and will switch the light back to dynamic in nature, so we can narrow down the issue to the static lighting being built into your map. You should check your lights themselves and look at their spread and intensity as well as their indirect lighting intensity. The glows you are showing in your picture look like static indirect lighting built into the level. If not your light themselves look at your materials and see if your meshes are reflected those colors in your level.

Thank You

Hi,

Thanks so much for the quick response. I did a bunch of tests tonight and it turns out it didn’t like me using Blueprints of my meshes. Not sure why that is. Once I replaced the blueprints with their root meshes, the problem went away.

Thanks for the help.
