Maybe you could upload the bus for OMSI 2 first so we can see if there are any bugs and then import it to LOTUS?
Like gt670dn said, what for? I've spent last 4-5 years developing the bus in OMSI, and it works quite fine in it apart from some missing features. But, due to personal reasons and some inherent limitations of what OMSI can do & handle, the project is now coming to LOTUS.
There are some 'bugs', such as the flickering shadows, but that's a LOTUS-specific thing.
