Hi @Senix
Unfortunatelly I haven’t been able to repro your issue.
Can you share more details regarding what you use as a BP Prop, which static mesh(es), what kind of parenting you are setting up ? What are your World Partition settings ?
In a blank map, using a BP prop on which I assigned a cube static mesh component, I have no issue
I created a child actor and assigned it another static mesh.
Enabled streaming, launched session. My actors are all streaming out properly.
Regards,
Seb
