    FINALLY, thank you for showing how to solve that compiling issue, since you (and I) painted the landscape the first time some of the shadders did not compile and it drove me crazy. You will never imagine how relieved I am right now.

    I'm having all kinds of problems with building lighting. First time I tried I just kept crashing after 4 hours. I reduced the amount of objects, and got thru a lighting rebuild, but then shadows were spread around willy nilly and not corresponding at all to a light source and I've had some foliage that just turned black. I turned off Cast static shadow and turned on cast dynamic shadow in the foliage tab in instance settings. I had the light rebuild do everything it was supposed to this time around with meshes I placed, but any foliage had no shadows at all. Everything is washed out, and there's hardly any difference with the shadows that do show up. I don't know if I missed a step, or what...but before the lighting build, everything on my map looked really good...then I rebuild the lighting and everything looks like absolute dump.

    Hello, everything looked fine until I build the lightning (BEFORE Build: prntscr.com/mcow51 //// AFTER Build: prntscr.com/mcovp5) Do you have any idea what the issue could be? (I don't have normal maps / roughess maps for some of my textures if that might be an issue)

    the textures might not be bright enough for the lights. also i found that not using static light and object dont need to be rebuilt. do the world setting option and also add a skylight if not present also after build it looks better

    Hello :) Does anybody know why the landscape in my level loses their textures when building lighting?

    say you have 3 levels streamed next to each other, cant bake them all at once so instead i bake them 2 at a time towards the light source so overlapping shadows are baked in, but even after that it says i still need to bake lighting even tho its all fine... and on top of that when all 3 are loaded in it adds this horrible added light into it all, screwing with all the bakes as if i added another light source and havent baked them. is there a way to fix this?

    hello, I have an issue building my lighting. I followed the instructions exactly, but my shadows are barely visible, and not black at all like yours are. The environment color doesn't make a difference, it's always is the same color; a barely visible grey. can you help me?

    ​@Roby Coltan light building is pretty tricky. light always builds on static mesh and not on stationary mesh regardless of light. i had a scene with no static mesh but various static light and no building msg.

    Same problem here.... and I turned off the auto exposure and nothing changed... XD

    I have auto exposure turned off on mine - that might be the difference.

    My build was taking more than 30 minutes with a good gaming laptop. I read online that you can change the foliage settings from static to movable to help make it faster. It made a big difference but the shadows looked horrible. Is there anything I should take a look at or change so that this doesn't take hours to build?

    You could try adding a lightmass importance volume (google it)

    Same problem, checking the swarm agent tells me that it's just taking an absurdly long time to process mappings. Not sure how to speed it up

    I fixed that by renaming the Save folder inside the project.
