So before Run time it looks like this first picture
but then during run time it looks like the 2nd picture
When I exit runtime it still looks like 2nd picture but if i slightly manually adjust the LOD setting it turns back to normal.
Anyone know whats going on?
Kind of looks like you’ve baked lighting with one LOD, but not the other. What kind of lighting are you using in your scene? Anything on this page look applicable to your setup? Unity - Manual: Lightmaps and LOD
