I’m kind of a newbie with this and I’m having some problems with the lights in the scene. All the lights are static (otherwise some wouldn’t work), and the build is only a preview, however in a production build the result is the same.
I would like to know why these lights aren’t calculated and why the light spread disappears. I’m posting screenshots so you can understand better the issues I’m dealing with.
This is before the build (or bake)
This is after.
I appreciate all the feedback I can get, so thanks
I tried all of that and the lightmap resolution is up to 512.
Regarding the lightmap UV’s it seems strange cause there are a lot of different objects and none of them calculates the light correctly.
However there is an error that happens and that constantly requires that I clear the lightmaps, but that only happens if I do two builds in a row. In mapcheck I get “WorldSettings_1 Maps need lighting rebuilt”, which I do. I clear the lightmaps and I build the lights again… and the problem disappears… until the next time :(.
Less than this and it probably won’t calculate anything. But I tried it with 0.1 and the result was the same.
The thing that is bugging me is that it seems that the light isn’t baking correctly in the textures. The spotlights loses their highlights and subsequent shadows. I even increased the spotlights values because I was considering the dimming of the light in the bake, but it still doesn’t stick.
Have you tried copying your scene to a new project? I’m not sure exactly how to do it at the moment because I’m not at my UE4 PC, but it seems like it might be a good solution if your friend was able to build the lighting without problem. There has to be some forum posts explaining how to do it.
I haven’t completed the migration, but I’ve copied the content and tried out some objects and the map check errors still continues and it seems that some of my objects aren’t building the shadows correctly.
I’ve managed to complete a correct light build by lowering the lightmap resolution of the objects, and tweaking with some properties like “indirect lighting smoothness” and bounces. May this have anything to do with my rig? I have an old I7 with 8 threads at 3.4Ghz and a 970 GTX.
I would to polish the shadows and the lights but since this is so unstable I’m reluctant.
Apparently the error was due to the texture pool size that by default is 1000. I increased it and it seemed to work. The behaviour is much more stable. Also I dabbled with the lighting static mesh resolutions.
It seems to work, and I hope this is the end of this problem.
Thank you for the feedback and the support, it was really helpful guys ;)!
I’ll leave with a preview of what I managed to get, and also could you help me with the light spread in the wall so that it doesn’t get so jagged.
