Lightmass (?) issue..

Hi there,

Please have a look at the screenshots and check the pipe insulation. When I assign the material in preview mode it shows it properly and when I make a lighting build it comes up with the results in the other screenshot. Even though I raised the lightmass resolution to 4096, I have created different objects (all piping insulation was one object and splitted that in 5 different objects) still I can’t get the material to be applied properly. I have checked the normal in 3dsmax, modified the geometry (convert to editable poly) but still no luck…

Any ideas?
