Area Light lightmapping problem

Hello, guys.

I dont understand, how can it be possible (look at screenshot1). One of the of the edge of “C” sign has a light :shock:… there is no any light, its something with a beast. Has anyone encountered similar problem?

My lightmapping settings are:
mode: Directional Lighting
Quality: Hight
Bounces: 4
Sky Light Intensity: 0
Bounce Bootst: 0.25
Bounce Intensity: 0.25
Final Gather Rays: 500
Contrast Threshold: 0.022
Interpolation: 0.262
Interpolation Points: 16
Ambient Occlusion: 0
LOD Surface Distance: 1
Lightmap Resolution: 50
Lightmap Padding: 1

Lightmap UVmaps were generated by Unity3d

Try messing with either the padding setting or the lightmap image’s compression/resolution.
