Stuff unloading along the way

I have rigged and animated a Camera Part, for cutscenes. What I did was to animate it going a bit fast on roads, but I encountered a problem. The problem is that models (UnionOperations) are unloading along the way. Any idea? Video with issue (it may be hard to see)

I have put the character hidden in the middle of stuff happening, since probably that would cause chunk rendering, but didn’t solve the issue.


It might be because your union’s render fidelity is set to automatic.
