I wonder if it is possible to see large object groups only when rendered. I do not want them to cover too much space. Or is there any other options for me to manage them. Objects are surrounding buildings.
The easiest way would probably to put them on a separate layer and turn that off when you don’t need them.
Worksession might help with the objects in a separate file. I don’t know how Worksession works with rendering.
I am glad to find a solution to my problem. Here is a link of the youtube video that explains how to manage large files.
