Of course I am biased, but in case you where wondering…
There is some information here
A short answer would be
- aniMate2 is an NLA(non linear animation) system
- keyMate is a linear animation Interface that operates on DAZ Studio’s keyframes
What does that usually mean for the user?
- if you want premade animation segments(called aniBlocks) use aniMate2. A “lite” version is included with all versions of Studio. Purchasing aniMate2 allows editing of the keys inside the aniBlocks.
- if you want to create from scratch and/or are used to a traditional animation system. keyMate is what you probably want.
