Okay,
first of all, jasmine44, this is not a 'chat room', so do not expect instant answers. It sometimes takes hours for someone to answer your question.:original:
Second, ES stands for Endangered Species pack and AA stands for the brand-new (this week) African Adventures pack. Since you don't know what those are, I'm assuming (always a mistake) that you do not have them.
The way the Design Team suggests you start editing is not with an animal, but with a
stationary object (like a trashcan or bench). It's much, much easier and you'll get to know the files, and where they are, better.
Then try making a
variant (extra) skin for an animal.
Then try doing your first animal.
In our Downloads section there are several guides for these things. For objects, try Penguinman's OCT (Object Creation Tutorial). For animal variants, use his VAT (Variant Animal Tutorial). When you're ready, download Sideshow Bob's APE II tutorial for making animals from scratch. When you've done any/all these things, you'll have many, many questions. You can post them here, or visit
ZT2 DC which is a site devoted solely to designing.
Hopefully this will get you started correctly!:original:
