Why you need Project Skyline?

[iamVFX]

When engines would do the same thing by default?

[Letterbox]

it still looks overly complicated, but its a great idea.

An alternative to skyline? a) is skyline available? b) can unity export it back into SI?

[nuverian]

No unfortunately you can't.
We are using this at work. It needs some improvements allthough its very nice.

[Bellsey]

The Unreal engine also has a similar feature/tech, but again its isn't quite the same etc.

[luceric]

It's pretty similar. And that's expected because this sort of thing is where things are at, or were going to be soon, in terms of animation tech in games.
