I posted this question at answerhub but I didn’t get any response so I’m trying here instead. Lights (point light in this case) looks fine when I move them around the scene or change parameters for them. Like in this picture, the light spreads smoothly over the building (a static mesh) and looks somewhat realistic.
Then I hit the Build button. And the shadows become blunt and sharp. There’s no smooth spreading of light anymore. I can then move the light around a little, or change a parameter and the light suddenly pops back to normal as in the picture above. But this is what it looks like after I hit Build.
I get a feeling that I’m doing something fundamentally wrong here. But I tried increasing the lightmap resolution on the mesh to ridicilous values. It’s actually at 2048 in the last picture. Plus, the light looks super fine in the first picture. It just wont stay like that after I hit build.
