One thing that is on my mind though is how niagara will be presented. Unreal helped me so much in regards to how presentable and imho easy to understand everthing is in the editor.
Blueprints - a visual way to scripting
Node system for materials/shaders - extremely intuitive rather than writing lines of code.
However, like a few pointed out before me cascade isnt really that and is starting to feel a bit outdated as it functions very similar to any other engine out there.
So is there anything you can tell us on how the philisophy of designing the new pipeline for Niagara have been to have a similar impact the other two I previously mention have had but now for vfx?
