I have a kmz-file containing 2 textured building models created through FME. When opening it in SketchUp it however only reads one model, any ideas why?
How about sharing the KMZ file so we can have a look at it?
A kmz is a zipped archive that may contain multiple files. I suspect that your kmz contains a mix of collada (.dae) and keyhole markup language (.kml) files. SketchUp is not able to import content from .kml, only from .dae.
Also, I am not certain what SketchUp’s importer will do when a kmz contains multiple .dae files. It’s possible it imports only the first one found.

The kmz indeed contains two .dae model files, and SketchUp imports only one of them. In a dae viewer, they look like below. SketchUp gets the second one. Are they what you expected?
Here’s a 2017 SketchUp file with both of them imported. To make it I unzipped the kmz and then imported the .dae files one at a time. They were originally right on top of each other, so I moved them but you should be able to fix that if needed.

I was afraid that SketchUp only reads one of the .dae-files. My final resulting file will have 1000+ models in it so importing them one by one is not the solution for me. I will try to export it differently from FME.
