This is very interesting indeed, now for us working as in-house Visualization most of the frustration is design changes and as mentioned by @, large project.
We work designing schools, hospitals and similar so there are many instances and repeated geometry that get lost when we export from REVIT to Max then to Unreal.
So far I have to do a mix of real-time lighting with bake lighting but still not optimal.
If this Project Nile can take care of that, it would be great.
A live link as if I move something in Max then it moves in Unreal would be cool but to us, it is more important to maintain a bidirectional work flow. I don’t know if this make seace Ken?
