Universal Fighting Engine

Unity currently ships with 2 types of animations, commonly known as Legacy and Mecanim. They both have ups and downs when it comes to use them on Unity in general, so here is a little Pros and Cons from both types and how they can affect your work with UFE.

Pros:

• With the use of a global humanoid rig system, you can virtually have any animation on any humanoid model
• Has an automated mirror system (better processor usage and no texture glitches when mirroring characters)
• Lots of extra options when it comes to minimal adjustments such as small rotation errors and root position

Cons:

• Each animation has to be carefully adjusted in the Animations tab of the FBX file, as they can suffer rotation and position errors during conversion to Humanoid rather frequently
• Animation preview in the move editor only works with the default avatar for that animation
• Because of the current limited access to Mecanim source, the work around used to control Mecanim animations is fairly limited
• Setting Interpolation Speed higher then 0 may cause some visual glitches
• Setting animations to a negative speed may cause visual glitches
• Animation Flow must be marked as Smoother if Mecanim is selected

Pros:

• None of the limitations posted above

Cons:

• The mirror approach used by UFE is not the best suited for complex model characters. Some normal textures might suffer visual glitches when crossing sides
• Because there are no tools to edit your animations you are highly dependable on its imported transform definitions
• Does not work interact with other humanoid rigs
