Ha, ha, hands of him he is my victim!
KnifeTheSky77 is right, Kimera is a little kind of a stress test when it comes to editing models. Download the latest version and use that exe (
https://mega.nz/#!3QdQ2QLa) It's a bit more stable when it comes to large files.
What you need are:
Kimera - for editing the models
pCreator - to convert 3ds files to p files
Bitrun - does the opposite converts p files to 3ds
imag2tex or iros textools - converts an image (the first for bmp and the second png) to a tex file or vise versa
All the tools are easy to use but there is no real tutorial for them which could make the start a bit rough. I recommend to look at APZ thread to see how a textured model could look like. After you have made familiar with the file structure I absolutely recommend to create some kind of a base model (we need a universal UV layout. Maybe APZ could help with that...) from were you (probably we) can work out all the models. Except for the main characters the hair could placed as a separate mesh on the head. And please use eye balls I have gotten an idea to make all models blink (eye closing) correctly.
