It's the latest Corona version with the latest Max.
Yes, probably that's the issue, but that sounds stupid to be honest. If you place your camera inside a wall and use clipping to render the scene, you can still render it without issues, it will realise that even though you are in the wall, there's clipping on, I mean that's the whole idea of the clipping...
As for what I'm aiming to achive: I can use different lenses because I'm further away from the scene. Obviously it's just an artistic choice and I still managed to render the scene with placing the camera next to the aquarium, but it's still annoying and it's not consistent with the way it works in other situations.
