Why Objects imported from Google Sketchup "FBX" falls through Terrain ?
I'm A VERY VERY VERY Beginner, first I Create a terrain, add texture to it, then on Google Sketchup I download any 3D model, or I create any shape, then I export them as FBX Files (I Checked "Triangulate all faces" & "Export two sided faces") Then I go to import a new asset and I chose the FBX file, I mark on "Generate Colliders" then apply, and drag the model to the scene, then I Add to it the Rigidbody component, I Press play, The Model Falls through the terrain WHY?!

use primitive colliders mesh colliders are not performance friendly
Put a collider(s) on the car, if you haven't already... (not seeing it in your screenshot)
You are getting an error in your statusbar - I would look into that error, it may have something to do with your issue.
The topology for that car is really crazy. It's a mess of polygons. I would retopologize that car, or find a different car that's a game mesh. I wouldn't be surprised if that was messing it up.
THAN$$anonymous$$ YOU!!! I Looked on how to fix the error and that solved it! :)
The simple answer is that you could try raising it up a tad. If you didn't raise it up just a little after dragging the object in, it is likely for it to fall through because the terrain and your object are already intersecting.
