I tend to agree with this. Blueprints tend to be very messy.
It doesn’t help that the example content isn’t always offering the best presentation. For example, 90% Megascans assets created before UE5 contain master materials with disconnected displacement nodes for tessellation effects.
It would be ideal if Epic went through these assets and created UE4 versions with tessellation, and UE5-ready versions with POM as an alternative rather than just leaving these materials with a bunch of loose nodes.
I think sellers see these examples and figure they don’t need to put too much care into presentation. They’d be right too since these assets get posted.
