In your reply you daid you have an Xtra to copy the binary data of a texture and save it to a jpeg. Have you made this available to the public?
I have a project that has come back to haunt me from almost 8 years ago that Ihave the director files but none of the 3DS files or the textures. They want to update some models in the game with updated textures so now I'm trying to figure out the best way for me to move forward. Of cours I've attempted to copy a texture as an image to a new member but that fails. So if you have available the Xtra that you are speaking of I would be very interested in it.
Noisecrime has a texture extractor movie that uses ByteArrays:
It works pretty well as long as you don't need the alpha component.
