HELP - Unwrapping a model with textures 
By Nemesis2001 on Mar 10, 2002 05:13 PM
Hi everyone,

I have been modelling for quite some time now, but i have reached a stage where i need to make a texture biutmap of a particular model, they model is going into a game engine, so the texture needs to be "wrapped" onto it, i have tried many ways of unwrapping the texture from the model but have had little success, i used Textporter to unwrap the model, and it appeared to do it... sorta, but it didnt have the textures. What i would really need is this, to unwrap the whole model with the existing texture still onit so i can render that from the top view and save it as the bitmap which will be used by the game, i have heard of programs that unwrap the model for you, and then u can "paint" on the textures, but i just need it unwrapped with the textures that are already on it. Is there anything in MAX that can do this? or will i need a speciel program?

Any help would be appreciated,

Thanks,

There is no program that will just unwrap it for you, that I am aware of.  Did you apply the textures that are already on it by using material id's for sets of polygons?  You are going to have to apply a edit mesh modifier to the top of the stack and detach groups of faces from your model.  For example, detach the front of the head, the sides of the head, and the top and the bottom of the head.  Then rotate sides, top, and bottom until the are all facing the front view.  Then use the scale tool to scale each of the faces so that they are almost the same size as they would be on the regular model.  This is neccesary, because when you detach the side of the face and rotate it it will still be curved a little, which will make some of the faces a little smaller in the front view than they would actually be in the perspective view.  Once you have rotated and scaled each group, reattach them so that all of the groups are connected.  Then apply an unwrap UVW modifier to the stack.  Your texture coordinates will be in place now.  Next render in the front view and your texture will be rendered.  Then you can save it as a bitmap, delete the edit mesh modifier and re-apply the saved texture.  Sounds complicated, I know.  If you want a better explanation, buy this book.

It gives a detailed example of the method.

Chiliskinner will unwrap the model for you (thoe mesh itself, not the UV's) - it's a script, not a plugin though. I personally don't like the way it works, especially on anything over 1000 poly.
