I went through the tutorial " Quick Start" level design using version 4.9.1 and found that each time I’ve placed the Lightmass Importance Volume onto my map, my Build Progress Bar always stopped at 88 %. To let you know, this is a very small beginner’s map ( see details below) :
- Rotation and Location for the Box Brush are set to zero and scaling at 4,4, 0.1.
- The only other light source I have are the default Directional Light and Atmospheric Fog.
That is all- I have no other Actors on the map . I have tried to lower the Lighting Quality from Production to Preview Level prior to initiating the build, but once the build process started, it hangs at 88%. I repeated the above process again, but this time took out the Lightmass Importance Volume, and everything builds completely at 100%.
I’ve decided to duplicate this process using the previous 4.8.3 version and it seems the build process went through without a hitch ( even with the Lightmass Volume scaled to cover the entire area). Does anyone have a similar issue?
