What is this... thing?
The Slightly Altered Muscular Male Mesh Mod (SAMMMM) is exactly what it says - an alteration of Maxis' nude male top mesh for Male Adults, young adults and teens that changes a few vertexes in the body to give it a slightly more curvaceous shape instead of the near-cylindrical default Maxis torso. No more wondering how your Sim's pants can defy gravity without a belt or strong elastic.

SAM4v1 was released early in the life of the Sims 3, before any substantial modding had happened. I originally assumed that better body mods would come along and the mod would be swiftly deprecated, but 4 years and many expansion packs later, I still get messages requesting additional features, so I thought the mod required another update. My understanding of the human male torso has also changed, which is why the mesh tweak no longer results in a smooth hourglass contour and is more subtle.

Maxis has changed the way bodies work from the initial release, but unfortunately, Sim males still have a popcorn-bucket shaped torso mesh by default, which looks terrible to me whenever the male Sim goes shirtless.

Questions you might have:
Q: What's the difference?
A: A picture is worth a thousand words.

Q: Aren't there already sliders for this?
A: Yes, I'm very aware that Waist and Hip sliders have been made, and I use them in conjunction with SAM4v2 (they're compatible!). However, replicating a contoured male torso with the waist sliders I've tried and the vanilla mesh usually results in the Sim's hands regressing into their thighs, which results in very strange idle poses and animations. A more fundamental mesh tweak like SAM4v2 averts this problem.

Q: What files does this affect?
A: This package changes the 3 bare-chested adult male meshes under underwear/sports/swimwear, and the one male teen barechested mesh. Additionally, it will use the mesh for the "Burnt/Singed" model after your Sim has caught on fire or been involved in an explosion, but that's not something most people spend lots of time in. It does not affect any other mesh files, so the silly "Plant" full-body costumes that came in University will still have wonderfully cylindrical tube-bodies. I don't know if it works with MerSims or Supernatural sims - perhaps you could tell me!

Q: Does this work with my custom skin mods?
A: Yes, and I encourage it. Here's an example with a widely-used popular skin by ephemera69:

The contour of the male torso mesh has been outlined to emphasize the differences.

Q: Does this require any expansions?
A: No. This only uses vanilla meshes.

Q: How do I remove the mod?
A: Just remove the package files from your mods folder. They all start with "sam4v2", for your convenience.

Q: I've got an feedback/a suggestion/an aesthetic opinion I want you to hear.
A: Please stick it in the comments section before I get distracted. I'd like to make sure version 2 is working issue-free in case I accidentally vanish off the face of the internet again, so any feedback is most welcome.

Q: Are there better male body mesh mods around?
A: Probably? I don't know, I've tried using Google, but the lack of hits seems to suggest that they all reside on more um... "specialised" sites that aren't really safe-for-work. Not that I'm recommending you go look - especially not if you're a minor. Otherwise, SAM4v2 is just a minor mesh tweak, so it has exactly the same number of polygons as the default meshes and shouldn't impact your game performance at all.


This is a GLOBAL override mod, which means it will affect every single Sim in your game. If changes aren't showing up, try deleting your cache by running a search in the "My Documents" folder for the file "simCompositorCache.package" and delete it.

Step 1) Install ONLY the files you want.
I have a readme that lists all the files in the package, but in case you don't want to read it, I'll reiterate it here:

The main zip contains the following package files:
Mesh files:

These four files are mesh files and will override every instance in the game that the "bare top" mesh appears in the game. They can work independantly of the following texture modifications, so you can use them with Hysterical Paroxysm's skin texture mods without issue.

Default Textures for the mesh:

These files pertain to the default texture as shown above.

A zipped file called containing two texture files called:

If you want to use the "muscular" textures in the picture above, install these files, but do NOT install:

However, they share the same Shine map, so DO install

To uninstall, delete any file listed above. If you forget any of this stuff, there's a readme and preview pictures in the zip to jog your memory of exactly what you're deleting.

Step 2: Cleanup (Optional but recommended)
Delete any unwanted package files in the zip that you're not using to keep your computer tidy.
