A Question About Baking A Texture Projection

Hey folks,

I've finally finished the layered texture nodes for my model and now I want to bake them (so that I can move the model around). But I've run into a snag. I did what my instructor (and the book) indicated, which is to select the object in the scene (the geometry) and select the texture node in hypershade, then select edit/converto to file texutre (Maya Solftware). I set things to anti-alias but not to use any lighting. I also set what I thought would be appropriate width and height sizes for the final file and selected a Targa format. After letting it to the baking I did a preview and noticed that the baked texture was "wavy," for lack of a better term.

The question is: what did I do wrong?

Now the width and height that I set the output targa too were the same (making it a square). Is that possibly the problem? If so, how to I determine what size I should make it.

I'm terribly confused and my instructor/book is no help what so ever. Any help is very much appreciated!

BEFORE BAKING:

AFTER BAKING:

interpolation on iv space works a bit different than when projected, and thus if your uv is uneven in a region you will get something like this an theres nothing you can do about it except fix your uv layout.

Thanks for the reply Joojaa! I haven't the skill of time to rebuild the geometry so it looks like I'm going to have to keep the projections and group them to the object.
