Problems with Sketchup Models!

Unity Engine
1

Hellloooo, fairly new to Unity, but having what I think is an actual problem rather than a noob issue…!

I built a “set” so to speak in Sketchup Pro, and export it as an .fbx file, which I then import into unity using the asset manager… only problem is, half the surfaces are not there! They’re all grouped together in sketchup, then in Unity about a 3rd of the walls/steps/surfaces have just disappeared? Have I made any obvious mistake here?

Thankyou!

well somtimes a surface in sketchup turns grey, then u need to right click it and click reverse faces.

but yeah i also have some problems with sketchup models, when i import them into unity the textures gets all messed up and i cant seam to get any colliders either. my char can just walk right through the model.
