Apparently, Unity can have an option to render your character above everything else. This is super useful for instances of 3D characters jumping through platforms and being rendered on the top layer - rather than clipping through the platforms. - Would really be nice to have the versatility in UE4 to be able to do that.
An example of what I mean
EDIT: Since we have the new ability in 4.17 to do forward rendering - is there a way to be able to bring back the depth priority groups?
