== Header ==
== Format ==


The ANCS format is split up into multiple nodes. Each node defines a character - a model, a skeleton, and a skin - and then sets a number of animation-related parameters on each one. At the end of the file, after every node, is a listing of [[ANIM (File Format)|ANIM]] and [[EVNT (File Format)|EVNT]] files.

There's a very short 8-byte header before the nodes begin.

===== Anim Info =====
=== Animation Set ===
 
The Anim Info structure is a little unorthodox. It starts with an unknown 32-bit value, and then is followed by a set of values. There's one value present per Parm Info instance, and the type of each value corresponds to that Parm Info's Parm Type setting.
 
=== Particles ===
 
Note: if the flag value at the start of the node is 5 instead of 6, when of these values is missing. It's currently not known specifically which one it toggles, so be careful.
