Help needed with modifying existing IVAs and loading Spaces into Unity

[CItyrobo]

So, a little story: I was building around with some modded parts building some planes. During that time, I thought to myself: 
"Hey, those IVAs that I downloaded, that uses ASET-Props or RasterPropMonitor-Screens, look pretty cool, why not try to implement some of those features into some other cockpits that could need some love!"

So, here am I, installing Unity and Blender, setting up a new Project in Unity, installing the newest Part Tools. 

After looking up some Tutorials and watching some videos, getting some understanding how to create new IVAs, and then I thought:
"Hey, changing some given IVAs can't be too hard, right? just search for it in the Part Tools menu and click spawn"

yeah... well... turns out it loads, but not fully. it can't find some textures that are clearly there, and also is doesn't seem to find some props that are also clearly there.

 

I am using the newest unity software (2017.1.1)

so if anyone has an idea, that would be nice.

until then I am going to install Unity 5.4.0 and try again. maybe that helps...

 

EDIT : Untiy 5.4.0 didn't help either. same problem: the basic frame loads but is missing all textures. also things like seat_pilot and StorageBagA or similar are loading wrong and throwing errors
