First off - thank you very much for your brilliant solution,** Loushuang! **
For a long time I couldn’t realise, that the skylight should be set to static and I was wondering what is going on and why is there no difference at all…
Now that out of the way, as of 4.17, the light bake of my project takes quite literally - forever. I’ve replaced the 4.17 UnrealLightmass.exe with the appropriate one and the build process simply doesn’t get anywhere…
On 4.16 the job normally took about 8.5hrs. On 4.17, 6hrs in and I’m still collecting photons and sitting on 0.00%. The project’s World Settings as well as the setting inside BaseLightmass.ini are identical between 4.16 and 4.17.
Any ideas what might have gone wrong?
