Connecting two models

I have two models for the same building, One for the interior and the other for the exterior. Is there a way to connect the two models without crashing because the interior model is large. I am trying to render a shot from the exterior with some of the interior elements through Vra.

Try importing the “Exterior” model into the “Interior” model. How large is the “Interior” model.

If you want the two models to register correctly, make sure that they are of the exact same size (both modelled with real size) and that they are standing at the exact same spot in 3D space.

Thank you Jean.
The interior Model is 99.99MB and the exterior Model is 40MB
