Made this tutorial for a friend, i do not know if there is a tutorial for this somewhere, so i made it myself.
Getting StartedThis is the guide on how to player model for gta3! so you can play as a player you want.
Tools:
TXD Workshop
3ds Max
To start:
Open up your TXD Workshop which you can download here.
Open it up and it should be like this:

then click Open IMG which can be seen here

Now, go to your GTA3 Directory which should be in either "My Documents" or "C:\Program Files\Rockstar Games\GTA3".
Go to the models folder and open up GTA3.img.
Extract Player.dff, and import it in 3ds max.
BUT! Make sure that before you import the model, make sure the toolbar is like this:

Now you probably have a ped you want to rig, so we'll carry on to the next step.
Now that you have extracted and imported Player.dff into 3dsmax, move it to the right/left away from the position that it was imported in.
Now import your model you want to rig to GTA3, for me, it's bmydj from SA.
Rotate the model + skeleton 90 degrees to the right, like this:

So now it should be facing the same way as claude's player model, after done, it should look like this.

------------------------------------------
Now, select all of your peds skeleton, use ALT to de-select the model, and Delete the skeleton by pressing "DEL"
So it will be like this:

Go to the toolbar; should be in the near top right corner. Click Editable Mesh and Element, select the whole model except the head, like this:

Now delete it so it will be just the head, as we are just rigging the head A-T-M.
like this

Move the head to where claudes head is, aline it up, so it will be like this:

But now, the neck area below the head will have gaps, go the the toolbar and click Vertices from Element.
Move the bottom area of the head where the neck should be to fit claudes neck without any gaps.
