There is a lot of informations spread out on this forum about lightmass settings but I would like to have opinions about what’s the general consensus/methods to achieve the best results in a decent amount of time.
Sometimes I tweak stuff without knowing exactly what is the interrelation between different settings. It’s hard to make all the test by myself because building the lighting often take many many hours!!! My pc almost exploded this morning trying to build my lighting and was still stuck at 0% after 2 hours. (it was still collecting photons)
General Lightmass settings include :
Static level scale (def 1) : I use .4 to .8
Number of bounces (def 3) : I use 100 bounces
indirect lighting quality (def 1) : I use between 3 and 10 here!
smoothness (def 1) : I use .4 to .8
Then there’s the baselightmass.ini :
this is koola’s settings (I use normal production settings for now)
Then there is the lightmaps compression : (I still use compressed lightmaps)
My question is, what part of these settings have the biggest impact on quality? is it the lightmass settings, is it the ini settings, is it both?
Are my settings overkill? It’s for arch viz (can’t have blotches and bad shadows and it’s for relatively small scenes). Please post your setup and discoveries about lightmass! The appeal of UE4 for architectural visualisation is that you cut render times. But if lightmass is going to take 3 days to compute lightmaps…meh we’re still gonna need a render farm lol!
