Can someone explain what is happening here
This model was originally crafted in Revit (old version now) and exported as 3D dwg format. I then used SketchUP to convert the model and then imported it to blender 2.79 (using a paid sketchup importer addon). Most of the model has come through fine, but some of my planes are displaying what appears to be a light source, but there is no light source. If I replace the plane with a new one, this doesn’t seem to happen. Obviously I can go through and repair what I must, but would still like to know what is happening here and possible fixes.
BTW have had this on other models that came via SketchUP - and the annoying thing is that it is only one some planes, say +80% of the model imports fine
