We have a fairly large project with several thousand rooms where we have started to see an issue with some of the ceilings. The ceilings will display a different model pattern than the one defined in the ceiling. We have checked to see if the pattern was over ridden or the ceiling type was changed, but this is not the case. When we check the ceilings we can see that the pattern is defined correctly in the materials. We have tried to override the pattern, so it will display correctly, but this does not help. The only way we have found to fix the ceilings is to delete the ceiling and model it again. This works but it i really inconvenient. Has anyone else encountered this same issue?
