Hey Vaishvik,
Level Instances containing Partitioned PCG Components aren’t properly supported yet so I would suggest not using this workflow if that is the case.
Internally we do use Level Instances but our approach is to generate “preview” data on the PCG Components located inside LIs and have parent Partitioned PCG Volume in the main map that gathers this preview data and outputs persistent data in the main map.
We do plan to add more support to Partitioned Level Instances at some point but even then with the builder those maps would still need to be generated on their own. The Builder currently will not generate data in multiple maps at the same time.
Cheers,
Patrick
