Light build gets stuck at x%. x depends on the complexity of the scene. Complex scenes will get stuck at 98%, a simple Level with only a Cube and a static light will get stuck at ~25%.
I did some research and did multiple things:
- Deleted and validated the SwarmAgent Chache.
- Reimportet the SM_Template_Map_Floor.fbx into my Project. (for some strange reason this was a bug in 2014-2016)
- Placed and Deleted LightmassImportanceVolumes → no effect
- “Force no precomputed Lights” and build light → it build light and everything was black, so it worked. if i try it now, nothing seem to happen, maybe because there is no light build in the first place…
- resized lightmap resolution of foliage meshes
- set up a test scene with only one cube and a static pointlight within my project → light doesn’t build
- created a new project → light build works fine.
So it seems, my whole project is affected by the lightbuild stuck virus. Should i create a new Blank Project and just Migrate all my stuff there, or is this a known bug and are there some easy steps avoiding this issue?
more info:
As you can see, my lightmap density seems to be ok.
I’m building on a 16GB 8x4GHZ PC, GTX780
The Light build is finished inside swarm agent 100%, but it seems to stop then and just idle…
Thanks for your Help,
