Here's another example - same project. These cabinet doors are modelled identically, imported identically and have the same material applied. However 3 doors shows reflection plus the drawer, while the other doors do not show nearly as much reflection. FYI the material shown here is the material that is imported. Once using a TM material the reflection problem does not improve. If I use another material from the 3rd party modelling app (SketchUp), these 3 doors still arrive with this reflection problem.
