This will only work in some situations. If you have a light which spawns into your level (say one that is part of a spawning blueprint), you will still get the warning. What you have to do is make the light movable. Movable lights do not require rebuilding. For something which spawns into a level, you will need to do this in a blueprint's event graph or construction script. Drag in a getter for the light, and from it a Set Mobility node which can be set to Movable.
When I get that message, I find it's the transform to the right, so I click on either stationary or moveable, then it disappears, the message. I've noticed I rarely need to build lighting.
well yeah but then you only use dynamic real time lighting, which is heavy on performance, not to mention with baked lighting you get lot better results due to the proper indirect lighting and light bounces
The error message also goes away if you change light mobility to Movable from the details panel. But is it safe? Which one is correct for a finished game?
Great vid Matt but in my case I have 23k unbuilt objects, and when I start the rebuild it gets stuck on ExportingLightQuality at 100% and doesn't go to the build. Any ideas? Thanks! ;)
@@MrTreeGuy If it were only that simple. Adding a lightmass volume changes nothing. Also this happens only on this project. Could be because the scene has a lot of meshes?
Hallo Matt The video was great as always but i have a question i made an entire 3d Model of my School for a School Project i imported everything into unreal and everytime i build the Lighting unreal chrashes because i am out of VRam because my Pc isnt that good do you know any way how i can build the lighting without unreal chrashing? Thanks :) Edit: I had an Idea that i send the Unreal File to a person that has a better pc and then he bakes the lighting and sends me the project back basicly like a rander farm
You could try to use the SWARM server... It's a bit hard to get working sometimes, but you might want to look it up if you don't know what it is. Good luck.
Are you placing static meshes or something like a bulb into the level, which are creating the build light error message, if so to the right of the screen around the 1:52 where Matt places Cube(3) in, the part that says Transform, press the tab that says either Stationary or Moveable, this should remove the message, it might not work for everything, but it will for most things.
Lightning builds usually takes too long even with the high-end CPU's unfortunately. But if it isnt finishing then something went wrong about your lights.
No of course not !!!! It's either because your game is very huge with so much lights or because of your graphic card is not good enough And I think the second one is more possible
