Lightning bug 43543543

Hey everyone! I’ve got a problem with my building of light. On this similar object there are some several bugs. How to fix them up and make my lightning smooth and cool?
The scheme I imported to u4 was:
Building 2 UVW maps (for two channels, 1 of which is for lightmap) , baking a occlusion in xNormal, then I added my model and occlusion to it. Here’s the result. I heard that I should change my lightmap resolution for this exact model in u4, but what exact value should I choose for it?

Hi!

The default value of 32 means the lightmap (texture) will be 32 by 32 pixels in size (that is pretty small). This should give you and idea of what texel density you should use for lightmaps regarding texel density you chose for your project.
