Bright spots in my lightmap.
polycounter lvl 11
Hi everyone. Recently I've been having this issue where I get these really bright colored spots across my lightmap.
The scene is pretty simple. It's got one DominantDirectionalLight and two PointLights. It also has a SkyLight but it's only dynamic so that shouldn't effect the lightmap.
I've had a few cases where I can eliminate the spots by turning on Force No Precomputed Lighting and then rebuilding lighting in order to scrap all the existing lightmaps and then turning it off and rebuilding again, but it seems to only work at random.
The PointLights seem to be the culprit since the bright spots inherit their color (tested by changing them to green), and the error didn't start appearing until I brought the point lights into the scene. I'm not sure what kind of settings are causing this issue since I left them at the default setting.
The scene was initially in one of the daylight lighting templates but I changed it to a night scene, but all I really altered was the color of the DominantDirectionalLight and added the two PointLights.

If yes then remove them, from my personal tests they give a lot of errors when building the lighting, lightmass seems to have some problem building the lighting with them.
It's a sort of random error, so sometimes you just have to rebuild the lighting, again and again. I remember one map where I had to rebuild the lighting 10 times to get rid of the problems.
Also, the March 2013 beta doesn't exist.
I tried setting the Emissive Boost setting to 0, but I'll try to disable emissive in the material itself when I get home. Thanks for the hint!
And yeah I meant Feb 2013, oops
I would suggest remove all material and textures from your scene, import it into new file and use standard night setup of UDK (you know when u start UDK it show that screen for light environment) Than make a grey texture (simple color with grainy effect sort of concrete in Photoshop or any tool) than add point lights and hope for the best.
