Cannot Capture Thumbnail on Blueprint actor - UE5

Hi there,

I have a problem not sure if this is an Epic bug but I cannot capture Thumbnails selecting Actor Blueprint in UE 5.1. They just look Empty.

On the same blueprint in UE 4.27 works fine

Is there a way to fix this?

Did you manage to do it? I’m looking for the same thing

any clue on this?

Blueprint Actors have their own 3D Thumbnail.
if you open up the BP, at the very bottom of the class defaulta, you see the thumbnail settings.

to give a BP Actor a custom thumbnail, mostly a Plugin is needed… like Custom Thumbnails.
This again don’t generate Thumbnails on their own… but you can add an Image (Screenshot or Icon) as thumbnail to any BP Actor
