Hi sup-dekra45, Lumion 7.5 was released before SketchUp
2018 and the SketchUp
developers changed the file format in that version.
So for that reason, please save the SketchUp
file as a 2017 version:SketchUp -> File -> Save as -> SketchUp 2017 format
This tip is also available in section 3 in this article:Knowledge Base: Model import guidelines for SketchUp
