What's left to get this into MSFS from SU

So I created this apartment building in SketchUp. Took me 15 minutes. It has two colors and 4 texture pngs. I basically created 1 floor and then extruded it up until it had the right amount (plus the little extra housing on top for the elevator machinery).

Now I can bring this into blender as an STL, but without the textures, and I fear I’ll spend more time getting the textures back on than it took creating this whole thing in the first place…

No easier way?

There are three of these buildings missing from a place I fly quite often, and adding them would be a fun little project (I thought)…
