Hierarchical Instanced Static Mesh (HISM) not rendering in 5.5.1 until Editor UI is clicked

Thanks for confirming the bug. :+1:

Are you using my asset (Floxy) or your own asset/implementation?

It would be supportive confirmation to Epic if the issue is also ‘independently’ affecting your project.

I submitted a bug report back in December (Case # 16208557) but haven’t heard anything yet.
if you haven’t done so already, it would be helpful if you also reported your own bug to Epic so there is more attention on the issue.
