Uhm… hello guys… i am currently learning unreal and i think this might be very basic problem but i can’t able to solve it… i had this issue with light baking…
before building my lighting the scene look like this…
so i thought and as i read somewhere baking this helps us to create a map that stores the lighting details so even if we can remove lights after baking the scene remain lit since it’s all baked and helps us improve the performance
But after clicking the “build lighting only” the scene look like this
it’s like the entire lighting is gone…
i don’t know where i am going wrong…
i set all my lighting to static,
I disabled Lumen
I disabled force no pre computing in world settings
I even added lightmass importance volume (not sure what it does but saw in some 4 year old video that he added it for baking)
I did not understand what you mean by “what sort of level” … if i assume right then it is just an interior room (a dark room and i am trying to create kind of stylized lighting)… where the orange light supposed to be a fire torch and the blue light supposed to be the moon light coming from window…
(I didn’t build/bake lighting)
“static light won’t work with world partition” (I am very new to the unreal engine so i don’t exactly understand what this mean either… i am sorry )
but by default world partition is disabled and i watched few youtube videos but they didn’t mess with that either… but when they build the lighting it came so good for them but for me i am getting like the one i showed above
These are the lights i used in this room… apart from sky light everything is static… i am not exactly sure what lights supposed to be static and what are supposed to be stationary and what are supposed to be movable
Like the fire torch light (orange, point light 1) supposed to be flickering which means that light has to be not static but i can’t kept it in baking… I kept it just to see if the baking is working or not but the whole orange point light went missing after the building )
When you started making the level, did you choose ‘open world’ or ‘new level’ ( something like that ). If you’re tinkering with the default player level, then it’s WP, and static lighting will not work.
No i am not specifically trying to use Static lights… i saw that we can’t bake lights unless they are static so i turned all of them to static…
( to be honest i don’t know the difference between all three except the vague understanding of movable and stationary are used for dynamic lights such as flickering and stuff and static used for fixed lighting that won’t change no matter what)
wow… so if i re-enable lumen and set the lights back to movable then i can bake them without any problem? that’s new thing for me thank you so much… I will check immediately
oh… uhm? but i wanna bake them… since baking gonna optimize things… and help me give a lit room without lights… is baking wrong? why do i had to use lumen instead of baking?
Sorry, you’re giving me conflicting information here.
If you really want to bake, then yes, static, Lumen off etc.
But you only really need to do that if your target platform is low end mobile phones.
It’s a trade-off anyway. Yes, you have less lighting overhead for your level. But if its bigger than a few rooms, you have a large memory overhead to store all the lightmaps. So, its not a total solution.
static lights bake lightmaps and lightmap volumes. no dynamic gi or dynamic shadows.
stationary lights bake static gi and lightmap volumes. the lights can not be moved without invalidating. but you get dynamic lighting and shadows (mega) and potentially lumen on top.
movable lights don’t bake anything. everything is rendered in realtime. all mega lumen.
oh i see… so baking is for low end devices like mobile phone…
i am so sorry… i didn’t meant to give conflicting information… As i watching some videos regarding game dev i stumbled into “light baking technique” and it picked my interest so much that i wanted to try it but i failed so i just feel like i got to know how this thing actually done… that’s it
Yes, you really don’t need to worry about light baking ( static or stationary, thanks @glitchered ) unless you have a specific reason, or are targeting a specific device.
It used to be the case that it was a pretty standard thing to do, but basically nobody does it now, typically ( because it’s a huge pain in the butt ).
oooh… so stationary lights are good choice for baking…
so according to the lighting in the room… for fire torch lighting i had to use stationary light and the rest of lights to be static and bake it? but how can i solve that “whole lighting is missing after the baking is done” problem? any ideas
flaming torch… my bad had to be clear on that part… i thought it’s not possible but when @glitchered said we can also use stationary lights for baking i thought there might be a shot i can use that…
… if i assume right then it is just an interior room (a dark room and i am trying to create kind of stylized lighting)… where the orange light supposed to be a fire torch and the blue light supposed to be the moon light coming from window…

thank you so much… I will check immediately 
you don’t bake. Lumen, movable lights, no baking. It’s that easy!
no wonder they are not prefering to use this technique anymore lol
