Baked Lighting Artifacts

[t.coursey]

I need help ASAP if possible.  Trying to get a project out and I'm at the end, finalizing my baked lighting.  However I am getting these random purple spots in different places on each bake.  Sometimes they are not there, sometimes they are...each time in a different spot.

Has anyone ran into this before, have a known fix or workaround?  Thanks.

I can't comfortably bake my lighting at a higher resolution overnight knowing this may be in the bake.

Hi Trey,

It's hard to say what is causing such artifacts without seeing the test scene. Could you please zip your project's data directory and send it to some file hosting?

Also, could you please attach engine log file from <Project>/bin directory (usually called log.html).

Thanks!
