TS4 SimRay Body Modification - Enhanced Realism Edition
download on patreon Description TS4 SimRay Body Modification - Enhanced Realism Edition is an advanced overhaul of the classic mod concept by sirsleepy. This upgraded version moves away from cartoonish proportions, focusing instead on delivering anatomically realistic, highly detailed, and organic body modifications directly through the Simray.
Using a lightweight, non-intrusive cheat-based injection system, this mod allows you to sculpt your Sims' physics with gradual, natural increments.
Note on Game Engine Limits: Due to how EA internally handles script-based cheat commands, a visual update might occasionally delay. This is a hardcoded engine limitation, but the mod is optimized to force updates as reliably as possible.
Installation Instructions
Download: Download the latest release package from my patreon, link: download on patreon
Extract: Unzip the folder to look for the .package and .ts4script files.
Deploy: Move both files directly into your Sims 4 Mods directory (Documents\Electronic Arts\The Sims 4\Mods). Do not bury the script file deep inside subfolders.
Configure: Enable both Custom Content and Script Mods Allowed in your in-game Options menu.
Restart: Launch the game to apply the script registration.
Main Features
Realistic Scaling Thresholds: Each Simray blast applies a precision shift of ±0.25 (25% of the slider scale). For smooth, authentic, and maximum physiological changes, fire the Simray four consecutive times.
Advanced Pie Menu Constraints: To preserve immersion and realism, the pie menu is strictly restricted to Adult Sims acting on other Adult Sims. Age-inappropriate scaling is hard-blocked.
Realistic Upper Body Sculpting: Fine-tune the upper torso with natural weight distribution. Adjust chest settings (size, realistic gravity/heavy-light depth, separation, and inner/outer positioning) and realistic abdominal belly growth.
Organic Lower Body Physics: Sculpt authentic lower-body morphology including hip width, glute depth, inner/outer thigh thickness, natural calf definition, and realistic foot length scaling.
Dermatological & Body Hair Realism: Dynamically toggle authentic skin textures, ranging from hormonal acne outbreaks to perfect skin complexions, alongside natural body hair elimination.
Contextual Mind Control: Force highly realistic physical interactions (targeted cheek kisses, passionate kisses) and seamless wardrobe transitions (forcing bathing states or realistic towel wraps).
Enhanced Custom Sliders (v1.0.5+): Built-in native support for advanced custom anatomical sliders, perfectly synchronized with standard TS4 skeleton meshes to prevent clipping.
Requirements
The Sims 4 Base Game (Fully patched to the latest version).
Script Mods Enabled in the game settings.
Shout Outs
Deepest thanks to sirsleepy for the groundbreaking concept of the original 'Simray Body Modifications' mod, which served as the inspiration and core architectural framework for this Enhanced Realism project.
