Thanks

Here is what I'd like to obtain (here in redshift), the bridge hides cars at first floor

Is it possible in Octane ?

You're not rendering your Bridge. Its excluded. Render it with the bridge. Bridge and the cars have to have different Object Layer IDs. The hierarchy doesn't matter. Right click on IPR > View Layer
