Is it possible to conrol Nanite detalization manually?

I want to render a close object with details level of very far object. Is it possible?

What do you mean? If you want worse quality for some reason, lower distance field res on mesh

Can I do it at runtime dynamically?

Why would you want to make it intentionally worse? Also no, you cannot generate mdfs in real time.

I’ve discovered that in ue5 far objects don’t render properly with SkyAtmosphere. I’m thinking do draw really far objects as scaled miniatures in another depth pass to simulate drawing of very far objects.
