I just found a pretty interesting video where some of the developers of Rayman Legends show some of their tools and how they do animations and edit levels for example.
Nothing groundbreaking, but still some pretty slick features. I like especially how they create the walkable shape of the level, shown at 16:06. Fascinating how it magically maps textures onto it while changing the shape and still looking good 
Thanks.
Rayman Legends is a gorgeous game. I have Rayman’s Jungle Run for my mobile and it is so lush. That trick of morphing the ground is amazing.
Looks like triplanar texture mapping with some clever faces. I think ragespline has something similar too.
I was thinking of RageSpline. Very cool.
Rayman levels are beautiful that’s why i love these games
Wow that is good stuff, great to see how they put the game together. With Unity getting in-house 2D support soon I hope we see people creating engines like this for creating 2D levels that we will see on the asset store, the way levels are created in Rayman Legends just looks so fluid that you want to do all your games like that.
Wow, that is so cool. I’d be interested in a editor like that in a game, would be a real hit I think 
To see how they work is very inspiring!
Looks like what Spriter and Spine can do.
Neat. Think I’ll send this to some game dev instructors. It scratches the surface of a LOT of material.

Really cool video! Thanks for posting it. Like others have said, you can patch together a few different assets to do a lot of this with unity. (Ragespline, Spine, Smoothmoves, etc).
I’m using ragespline in my current project and in combination with the PlaymodePersist asset (which saves changes in play mode), I design levels and make changes while playing. It’s a quick, fun workflow.
Biggest monitor ever.
hello ,my name si liushaodong, Nice to meet you
I think its a very nice concept of " Level Designer first " and then decorators.
