Why are some walls still black?

…Every model I import from 3ds max when doing interiors has some black wall when lighting is built. I’ve checked the light mass uv’s and the look fine and the right channel selected. the resolution is fine. I’ve put skylight bounces up the 10 and indirect lighting up to 10.

Is it just corrupt geometry?

yes i’m just rebuilding will send when done. Noticed I have a few uvw modifiers on the black meshes in 3ds max. So collapsed them to see if its that - what do you think?
