This Tunnel modelled with cinema 4d r19. Many object made editable but some of didnt make editable. Bcs you may change how to want to use for Cinema 4d version.
However we put fbx and obj format. They are converted format. Bcs of that you have to change or reorginise light, texture and meterial again.
If you know 3D software a little you can make so many alternative with this model.
This modell not so big file size, you may use everywhere easily.
Thanks for interesting
