Where to attach instance components?

Development Programming & Scripting Blueprint

So, since instance components can’t be attached to template components, where am I supposed to attach them in a blueprint?

2

no one knows this?

Since upgrading to 4.4, we’re seeing this when trying to attach a simple scene-component to a SphereComponent.

Curiously, this doesn’t assert during the initial attachment, but rather during PostSpawnInitialize when entering a PIE session with Dedicated Server set.

Anyone got any ideas what’s going on?
