UE4
Blueprint system enables users to create different mode of Blueprints either a
level-based and class blueprint, whereas Grasshopper only has one system to
work on.
Both BP and Grasshopper uses components to give an end
result.
On BP user
interface has minimal features to work with especially to find a component
where search bar is the only option, whereas in Grasshopper it broken down into
tabs of dropdown menus making much easier to find.
The ability to see the components "fire" in real time is the advancement for
UE4 on visual scripting environment.
The input feature brining
the interactivity to the game mode making the whole design and
visualisation process more realistic and impressive.
