    i checked all the meshes, no UV overlap or anything,
    Actually in the log window, it goes to 100%, and all kinda photons take 0.0 to 0.1 second, but in the actual "Swarm status" it goes to 99% and stops.
    No error or any warning is shown !
    i'll change the udk's version to see if the problem persists.

    Edited : I changed the UDK version and the problem is solved. Lightmass took 1 min and 1 sec to build

    Sometimes a bad staticmesh, with no UV's (LightMap) causes that to happen. Or maybe the terrain?

    The lighting build info window, sorted to what's taking the most time could be of use. Though what you describe it doesn't sound like that.

    You could try copy and pasting the level into a new level, and see if that helps.

    Building lightning takes forever.

    As the title says, Swarm agent for creating lightning in the scene takes forever.
    My scenes is simple,

    -consist of 70 static meshes.
    -9 bsp brushes and 1 terrain.
    -all the materials used are very very simple, mostly consist of 3-10 nodes.
    -I have a LightImportanceVolume in my scene,

    I had much more complex scenes before, and it didnt even took me about 5 min,
    but this time, it goes to 99.19% in like 1 min, and stops there, i waited 3 hours
    and still it doesnt get completed, and it wont give me any errors or warning either.
    Last thing, i'm using April version of udk.
    Can anyone tell me what the problem is ?
Working...
