Can you explain how to do this?
Sure xD
First, you get the trophies from the game, they are in the toy folder
Then, extract them with ais (I first used another model extractor but I had to place every texture in a manual way, now with ais is much easier). You'll have a collada dae file and some textures.
Place the dae and the textures where you want them to be. Open the dae file with a 3D program compatible with collada dae format. I use 3DS max 7 I guess.
Move the camera to make it look the more similar to the original csps. Edit the lightings, edit if there's any issue with the textures (eyes are usually troublesome) and save. Every time you open that file, it will load the textures in that folder. If you change the location of the textures, you won't get them to work, so you need to keep those textures in the very same folder forever O.o
Any time you need to make a new csp, just change the textures in the folder for the ones of your texture, open the 3d file, and voila, it's now the textured character
Take a pic, edit with photoshop or similar, and make the csp from it
It really took some time to do this, I've been improving my technique and I'm now able to make csp's from a prepared 3d file in only 5 minutes or so
