You'll need a program that can import a Sims face as an Obj file and let you edit it. You'll have to research and see if your program can do that. If not, you can get a meshing program, like Blender, Milkshape, Wings 3D etc.

I tried with FaceShop but it doesn't work because the back is not developed. My question is whether they will develop it in the future?

The only people who could tell you that are the developers of the program.

My dad tells me if so much has happened so far, and it will.

I suggest making a theme for those who want to develop it so developers will see that there is a need for it and they will do it

For sim faces there is no backside. Ingame there is no hole because it is hidden by the head/hair mesh and the rest of the body.

This is a tutorial for making edits to TS2 faces, just so you are clear on that.

Then how are these sims made without a rear and why do they look so realistic with which program they are made? With MilkShape I don't believe it is. http://bulgarian-sims2-site.dir.bg/...=769026&dflid=3

Those sims are no doubt of it made in either TS2 Bodyshop or in game in Create A Family probably with custom face templates and/or by using sliders. (This tutorial is about creating face templates - an advancrd task.)
BTW Face Shop is an DAZ Studio add-on to create faces (obj-file and texture-file) from photos which also can be used as stand-alone application. I have version 7 from 2012 - the obj-files are different from those in the game..

Are they made of them sliders?

Why is this happening? http://prikachi.com/images.php?images/76/9621076s.png

You have to use the TS2 face mesh with an unmodified base (only moving internal vertices, not outer vertices, and you can't add/remove anything) if you want to modify faces outside of the game. The outer vertices line up with the head and neck, somoving these leave gaps. Adding or removing anything from the mesh will mess up the face expressions. Like I Said above, this is not a beginner project. Maybe start smaller, like making clothing meshes.

More realistic-looking faces are usually covered with skintones, eyes, hair and makeup that make the sim look more realistic. Sometimes also custom sliders to do things that can't be done in CAS or Bodyshop, but they aren't neccessary unless there is something you want to modify that the default sliders can't do.

And you should never edit the files in the install directory directly. It may cause issues in your game, sometimes to the point where you need to reinstall. In nearly all cases you have to make a new file with the resources you want to edit, and put the file in your Downloads directory so it indirectly replaces what ever you are modifying.

This Face Shop program does not sound like something that will work with TS2 faces, and I can almost guarantee there is no way of making anything other than a face extracted from the TS2 files work ingame if you also want the sim to have face expressions.

You have opened and then saved CASFace.package which is a very dangerous business. Normal procedure is Extracting your choosen item from a copy of the game-file. After that you make a new package and Add the extracted item to work on.

And always work with a copy of the file you want to extract from in the installation files, not the original one. If you make a mistake and the file gets borked, you may cause issues with your game without knowing it, and you may start seeing problems you can't fix easily.

I have another problem. Manicures are not shown in the game. Why?

Manicures? You mean accessory nails? Did you download any?

Yes a lot, but none of them are showing

Did you download the needed mesh, and did you look under accessories?

By the way, if you have issues with the game not related to this topic, you can post in the Help section under Community - - Social Home - - Sims 2 Help.

I did everything right, but it still doesn't work

Maybe their shelf life is over, or what?

Is there a contemporary way for making body mesh for sims 2?

Body meshes are the same as clothes, there's already several tutorials over in the Bodyshop/meshing section.

Okay,then send me here link with one of them.

https://modthesims.info/showthread.php?t=141997&page=1 This one is correct?

The Unimesh tutorials may be better (they use Milkshape and GMDC editing).

simmer22 please tell me how they do her nose in that form http://www.prikachi.com/images.php?...00/9665600k.png ?

How can I know?
I guess a combination of a skin and existing nose sliders, but don't ask me which ones.
