hello all,
I am developing game 3d game in
unity using java-script.

 here my role is as programmer i need to give the list

of things that should be designed by animator or designer.


  1. character,
  2. terrain
  3. animation on character

but i don’t know their formats and any specification
that i need to explain to designer.

please suggest me
where i can find such list that i can tell to designer to design.

my basic requirement is mobile game for ios platform in unity3d.


The links on http://docs.unity3d.com/Documentation/Manual/AssetImportandCreation.html have useful information. It is a good idea for the designer to become familiar with unity as well.
