Saving UV's into a file help

Blitz3D Forums/Blitz3D Programming/Saving UV's into a file help

Well, what i'm doing basically is this. I accidentally welded a model and unwrapped it. Then i was given a new model, with more animations, and i tried to apply the same UV's, but obviously the welding buggered that up. So, i've reconstructed them in blitz, using code.

Now, i want to open up the model file, and edit the UV co-ords in it using the new ones i have.

Basically, read in the .b3d. Find and replace the UV co-ords. Save the file. Does anyone know anything to get me started?
