I am trying to render an interior scene which has an acoustical suspended ceiling with 2'x4' lay in light fixtures.

3 problems I am having:

1) The orientation of ceiling grid displays 90 degrees opposite than what it is in the ceiling plan.

2) The orientation of the 2'x4' recessed light fixtures remain in the correct position, although not aligning with any grid pattern.

2) The color of the ACT ceiling is dark grey, even though I selected a lighter color in Accurender. I have also experienced this same effect (dark colored ceiling) with other project interior renderings.
