I could be wrong, but I don’t think you can check the performance of a specific blueprint.
Insights will give you an overview, that you can drill down into, on what is happening on a per-frame basis, taking everything into account.
The categories you get a based on what needs to happen for a frame to render, and doesn’t target individual objects.
If blueprints are causing a problem, you’ll know if from a simple stat unit command, because the Game time will be using more of the frame than the GPU.
I did see this post
which apparently shows you how to display actor names in the data.
