  • Updated compatibility with JSmithJ's rig; mod is now compatible with the latest version of his Enhanced Bodies mod.
  • The slider strings are now available in Russian, thanks to JSmithJ.


This is a complete default replacement for the eye mesh and textures for Sims of all ages and genders. The name is a callback to an old piece of CC I made back in 2022, my first eye texture replacement, which I wasn't very satisfied with.

Overview
I prefer for my Sims’ eyes to have smaller, more realistic looking irises. There are quite a few options out there, but I’ve never been 100% satisfied with how they looked.

On one hand, the vanilla EA eye mesh tends to stretch smaller eye textures, making them look slightly squared, and the occult eye glow creates an unsightly outline where the original texture would be.

On the other hand, aWT’s default replacement mesh does a good job at reducing the textures, but comes at the cost of sacrificing things like catchlights and occult eye effects. Buhudain does have a version of this mesh that restores them, but the catchlights can look a little wonky or jagged at times since the mesh wasn’t really intended to be used with them anyway.

Moreover, those defaults only had a LOD0, so in some cases where the game would use LOD1 in a few situations such as generating certain thumbnails, the vanilla EA eye mesh with massive irises would show up.

With all this in mind, I decided to try my hand at making my own version and ended up with a new mesh based on aWT’s eyes, which features the following:
  • A natural looking globe-like shape as opposed to a perfect sphere, which mixa97sr helped me massively with. Though not 100% realistic, I do like the effect it gives and it doesn’t look weird or out of place.
  • Reduced iris size, pretty much the same as aWT’s mesh.
  • Slightly smaller catchlights, which I find pretty cute.
  • Available for all Sims, Toddler to Elder.
  • Includes LODs 0 and 1, allowing players on lower settings to use these replacements as well besides being cohesive where the game uses LOD1.
  • Lower poly than aWT’s mesh, but still a little higher than EA’s, thanks to thornowl nearly halving the poly count from 608 to 320 triangles.

For the textures, I edited escand’s beautiful Tiffany Glaze eyes, which I’d already been using on EA’s mesh for quite a while. I made the texture a bit larger, similar to EA’s default size, so that it won’t look too small on my mesh, and made some other small modifications to the texture.

I’ve included a replacement for the face overlay for all ages, which combines textures from potatobuttcheek’s Eyelashes N1, Aikea Guinea’s teeth and missy harries’ sclera. The overlay also gets rid of the lip tint for female Sims and the sclera has a tiny bit of transparency that blends in subtly with the Sim’s skin color. It’s a neat little effect EA used with their own sclera texture, but I hadn’t seen it replicated in many other defaults.

Sliders
The SimEyes shader doesn’t support morphing, so I had to figure out a workaround to be able to incorporate sliders into the mod.

I came up with a replacement for all human rigs that adds 4 new bones for the irises and pupils, which can be manipulated via bone sliders. I’ve updated the mod to include this new rig along with three new custom sliders that work for all ages and genders: Iris Scale, Pupil Scale, and Pupil Shape.

The iris and pupil scale sliders work pretty much like their TS4 counterparts. The pupil shape slider gives your Sim a vertical or horizontal pupil, which can then be fine-tuned by combining it with the scale sliders. I thought it had potential for some cool effects on occult and fantasy-themed Sims.

The slider strings are currently available in:[list][*] English[*] Portuguese (pt-BR – thanks to Aeri!)[*] Russian (thanks to JsmithJ![*] Spanish (es-ES and es-MX)


Compatibility & Known Issues
Rig and Sliders
  • The rig will generally conflict with any other mods that replace the aurig, curig and purig _RIG resources, with some clarifications:
    - It is compatible with the latest version of JSmithJ's Enhanced Bodies for All Ages and Genders mod, as it includes the same rig as this mod does. Both mods can be used together without issues.
    - It is incompatible with ghost-17a’s anatomically correct rig. If you’re using it, you can delete it and use mine or Jvsmith’s instead, as they include the same changes to ensure compatibility with all mods that require the rig.
  • If you’re using ghost-17a’s or Jvsmith’s anatomically correct rigs, you can delete them and use mine instead as I’ve included the same changes to ensure compatibility with mods that depend on those rigs.
  • The sliders are only compatible with my mesh; they will simply do nothing if used on EA’s mesh or another custom mesh.
  • Conversely, my mesh is incompatible with other iris/pupil sliders such as aWT’s; they will not look right if you use them because they’re made specifically for aWT’s eye mesh.
  • The sliders were made with my own textures in mind, but are compatible with any other texture as long as it’s used with my mesh. They will look best on textures that are similar in proportion to mine.
Mesh and Textures
  • The mesh and textures are currently default replacements only. I don’t use contacts in my game, so I haven’t made a non-default version yet.
  • You can mix and match by using my mesh with other textures, or using my texture on a different mesh. For reference, my mesh reduces eye textures to about the same size as aWT’s mesh.
  • My mesh uses SimEyes shaders because I wanted to retain the catchlights and occult effects. I haven’t made a SimSkin version, but you can easily change the shader of the GEOM resources using S3PE if you really want to.
  • My texture is incompatible with Gruesim’s heterochromia eye mesh. It will look bad if you try to use them together.
  • The occult eye glow is a mess by EA’s design. The effect is slapped on the eye mesh without any awareness as to where the iris is actually placed; in fact, it’s not even aligned correctly on their own eyes. I hope to be able to fix this one day and make it work properly with any eye textures, but shader modding is not an easy or fast task, so please bear with me.
