Heh... I`m afraid it`s caused by the object itself, rather than by the location. I always had problems with C4D->B->LW workflow when it came to non point-modeled geometry. I will just re-model this rather clumsy object in Blender and export it to LW. This will save both polycount and file work trouble:)

Thx for your advices. I havent expected the LW exporter to be a Python script:P ...Though I do have Python installed. Pity Blender page doesnt clearly point out it requires 2.51.
