Thank you! I will try and tell you if it worked.

Thank you very much. Problem solved

Thank you very much. I'll try both options.

With Lumion and large files just break them down and import as separate .skp models. I did this for a gas platform and a processing plant in situ, with LPG tanker and pipes for days - gives you a quicker work flow as well when elements need updating/changing. Good luck. I am currently designing for UEFA events - most probably same pitch (so to speak).

You're welcome, best of luck with it.
