Lightmaps causing chaos

Kensey Quarantine

Hi there.
Im experiencing lightmap issue every time im trying to build lights.
I've recorded a video explaining that problem, here: [ame="http://www.youtube.com/watch?v=hyKXUfr552I"]Lightmap problems - YouTube[/ame]
You see speculars are doing well when lighing isnt built, and do some strange things when i building lightmaps.
Can u help me please? It really scattering my head.

Thats how 3ds max renders my model and how i want it to looks like in UDK (X+ Y+ Z+ normals in max, Y- in UDK ofc):

Higher and higher, we are going to Drill Up To The Skyes!

put a higher level of specularity with a multiplier and a single constant OR increase the lightmap resolution
