Ok, time for some HOTT PLAYER ACTION! YEAH BABY!
No, just a small tut on getting the player parts set up as a normal ped. Not certain it needs it's own topic, so we'll put it in here, and I'll edit my second post on page 2 to add this.
Player parts are found in models/player.img. Use IMGTool or similar to extract. You should also extract the tga's from the txd's off the models you will wish to use; jhericurl.txd uses the jhericurl.tga file. TXD Workshop (latest is 2010 version; get this from GTAGarage to avoid compression errors) should be what you want for this, though others should work as well.
1) Ok, first thing, Carl has five basic parts that MUST be used. Extras (jewelry, hats, etc) can be added later, but for now, Carl has a head, torso, hand, legs and feet. Haircuts have a head already attached, so don't pick a plain head and add the jhericurl head as well. Also bear in mind that many of the txd's have names that should clue you in to what dff it will work on; for example, the shirtb.dff will uses textures that have a shirtb reference; in this example I'm using shirtbgang, which is a green shirt from Binco I believe.
For my first Carl, I used: jhericurl.dff, shirtb.dff, hands.dff, jeans.dff, and sneakers.dff. Open Kam's DDF IO, and for all imports MAKE SURE THE A IS SELECTED (next to the Skin Character button). Let's start with the head, import jhericurl, and select a clump (1=ripped, 2=fat, 3=normal). Now you've got a head with a bunch of bones.
2) Select the head and hide it. Now select all (CTRL + A) and delete the bones. Import the rest of the parts the same way. Once you have a full body, you can add extras if you like, but do the same thing, hide the object, delete the bones.
3) Once you're doing importing and deleting bones, choose Unhide All. Your model will show up put together, but we need to attach the parts to each other. Click on the head and click on Editable Mesh in the Modifiers tab. Click Yes to the warning, and choose Faces in the Selection Panel, and select all (CTRL + A) to select all the faces. Now click Attach in the Edit Geometry section and click on the torso. Be sure to choose the second option in the dialog box, which should be match Material to Material ID. This is VERY important.
Now, CTRL + A again, and click on the hands, CTRL + A and click on the legs, and for the last time, CTRL + A and click on the feet. Now click on the Attach button again to turn it off, deselect Faces and click the Editable Mesh controller off (don't delete). Now your Carl is all attached, but the material needs to be applied. BUT NOT YET. You need to skin Carl first.
4) As I previously mentioned, I suggest you find a ped model that's closest to the one you're importing. This can be difficult, because Carl is shorter than most male peds, and has a thicker torso than all but the fat peds. VHMYCN was the closest I found, but there still needs to be a little work done on Carl's mesh to get it to match properly. Once I get one I like, I'll save it as a 3DS Max scene, and upload it somewhere for people to use as they like. But for now, just pick it up from step 11 in my mini-tut, listed here:
http://www.gtaforums.com/index.php?showtop...st&p=1057471714Go skin the character, STOP AT STEP 17 - DO NOT APPLY THE MATERIAL YET, then come back. Don't worry, I don't have to work until 1PM tomorrow, so I'll wait.

...
5) Ok, back? Good, so now Carl is skinned, and you verified this by moving around an arm or leg bone to be sure the mesh deforms with it. Sort out any weight problems by running a few animations then fixing as necessary. ONLY when you are ready to export should you put together the materials. Open the Material Editor and click on the first one. Click the Standard button to choose GTA Material, then click on the button next to color to import the tga (or bmp). Be sure to click the "show in veiwport" button so you can see what it looks like from there.
6) Most of the shirts have hands, but for whatever reason aren't working for me, so you'll need a torso texture for this. In my example, we will have 5 materials: jhericurl.tga, shirtbgang.tga, torso.tga, denimsred.tga and sneakerheatblk.tga. So in the next material, choose the shirt, and so on until all five are loaded. Now you need number 6, which will be a combination of all. Click on Standard and this time choose Multi/Sub Object. Now simply drag the material from the ball to the first slot in the menu, then do the same for the other 4. You'll now have 5 materials listed. Don't apply yet though.
7) Select your mesh again, and click on the Editable Mesh Modifier once more. Choose Faces for selection, then click somewhere on the head. Under Surface Properties, you can see what the ID is. DO NOT SET IT, just note the number. Do the same for the other parts, memorize them, write them down, take a picture, whatever. Now, deselect the Faces again, and deselect the Editable Mesh modifier.
8) Go back to the material editor and choose material 6 (the Multi/Sub Object). In the list, you will see your materials with an ID number. Referring to your previous list of ID's, match up the numbers; in my example, after attaching and skinning, my numbers were head 2, torso 3, hands 4, legs 5, feet 6. Yours may be different, but the point is to match the ID's up, so for example, my first material (jhericurl) has an ID of 2, so I change this in the ID box. Do the same for the rest; you may need to move some of the unused materials ID's around to make sure there are no conflicts.
9) Once your ID's are all set, drag the Multi/Sub Objects material ball onto Carl. If all worked well, all his parts should show up textured. This needs to be done so the model can tell the game what texture goes where. If it all looks right, select the MESH ONLY and click on Kam's DFF IO, Skin/Bones Export. I named mine carl.dff; whatever you name it, make sure your txd will have the same name.
10) TXD? What TXD? The one you're about to make, silly. In TXD Workshop, click File/New, and choose 32 bit. Click on the blank image to select it, then import your first image, in this case, jhericurl.tga. Now double click on the image panel (with the internal name, showing tga at the moment, and the alpha and compression. Here, you MUST change the name to the same as the tga (or bmp) file (if it has an alpha, be sure to use that name plus an "a" at the end, typically). Then click the Compression check box as click ok.
11) Do the same for the other four files (more if you added extras), but in these cases, use Image/New, so they go under the first one. Again, 32 bit, import the image, then change the name and add compression. In this example, all 5 images are listed. Now save the TXD as the same name as your dff (in this case, carl.dff).
12) Add the txd and dff your gta3.img, rebuild, and use your coder of choice to load your actor in game. Not getting into that here, head over to mission coding to make that happen. You could also change one of the ped.ide lines, and you'll get Carl as a random ped.
If all went well, and you used the files I listed, you should get something like this:

Good luck, have fun, and happy modding!
