What is SimMotion?SimMotion is a set of animation overrides that adds realistic movement to your sims' anatomy (as well as reducing body parts clipping in official animations). Let your sims' penises, testicles and breasts swing free!Is SimMotion compatible with other animation override mods?No. Any files that edit the same animation resources will conflict, so you should only use one in your game (unless you have a mod that edits specific animations not included in SimMotion).If you have a package file in your game that edits some of the same animations, you will see the edits from whichever package your game reads first - mine or another creator's. The game will not mix-and-match overrides from multiple creators; for example, you can't use the showering penis animation from SimMotion and the showering breast animation from another creator.There are animations missing from SimMotion!The game includes thousands of animations, and editing them all by hand to reduce or remove clipping and add realistic movement is time consuming. I absolutely intend to add more animations, giving priority to a) things I want for my own gameplay and b) things my patrons ask for. If there's something specific you'd like to see added to SimMotion, feel free to leave a comment or send me a message letting me know what you want included so I can consider it.Does SimMotion work for all bodies and other anatomy mods?Breasts and hard penises will probably work well, but soft penises by other creators are unlikely to work with SimMotion based on how my content is set up.IMPORTANT NOTE:SimMotion animations will never be as perfect as I would like them to be. In part, because the game doesn't have soft body physics and collision (like what happens when you press your finger into your arm). In large part, the rigs that have been created for sex mods such as WickedWhims are not set up to accurately mimic all anatomy, such as flaccid penises, so the movement of some parts will never look like they do in real life.Also, for technical reasons, animations can't entirely account for sim body morphs. My animation overrides are created with medium Simdulgence anatomy and will look best on sims with average weight and muscle. Sims with larger anatomical parts or at different weight/muscle values may not look as good. There isn't much I can do about this, sorry!INSTALLATION NOTES:All animation overrides are contained within one file. If you want to remove SimMotion, you can safely delete it from your /Mods folder at any time.simdulgence_SimMotion (REQUIRED)Contains all SimMotion animation overrides.simdulgence_SimMotion_NoBreasts (OPTIONAL)Contains all SimMotion animation overrides but without breast movement. Use the default file OR the NoBreasts file - DO NOT USE BOTH. The NoBreasts file has the same limitations as the default file, so it generally cannot be paired with other breast animation override packages.CHANGELOG:2026-04-19: Added Natural Living meditation overrides. Adjusted some existing idles for better animation. Added a second version of SimMotion in a separate zip file - this version does not include breast movement and will only animate a sim's penis/testicles.The NoBreast version still has the same limitations as the default file; I've included notes about this in the post above. If you use other animation override mods in your game, and SimMotion and the other mod override the same exact animations, your game will use whichever overrides it reads first. Any overrides that are not the same - eg a showering animation from me and a vampire animation from another creator - will both display.2026-03-21: Added breast movement to stairs animations (walking up and down stairs).2026-03-19: Added overrides for fairy flying. This includes 60+ animations that make up fairy locomotion, including "hovering", "flying" and "gliding" across the range of emotional states (for example, angry hovering) as well as the pregnant flying animations.2026-03-02: Added overrides for all yoga poses for the yoga mat. I hoped to get these out a bit sooner, but the yoga animations are extensive and have quite a bit of complicated movement to them, so it took more time to polish them off than I expected - sorry! 2025-09-05: Added overrides for squat toilets, privy bushes, werewolf territory marking, and a variety of idles across the game, including in CAS. (Note: going forward, all overrides - including those in today's update - contain breast and penis movement unless it specifically says otherwise!)Alongside work on a number of other animations, I'm also working on overrides for the following requested animations: ghost abilities, yoga poses, treadmills, and breast movement for earlier SimMotion overrides that lack it. If you want to see other specific overrides added, feel free to leave a comment or send me a message!2025-08-27: Added breast and penis movement overrides for werewolf walking/running interactions from the Werewolves pack. You can see these overrides in action when your werewolf runs around at full fury or when superspeed is activated.2025-08-16: Added breast and penis movement to the Natural Living "sleep on ground" and "bathe in water" interactions from the Enchanted by Nature pack.(As a note - I'm really sorry this mod hasn't been updated for a while! Animations are one of the hardest and most time-consuming types of content to make well, and my perfectionism - or attempts at such - doesn't make them any easier. I'd love to add more overrides to SimMotion, and will try to offer more frequent updates with fewer animations in order to continue making progress.)2024-10-27: Added breast and penis movement overrides to animations on the beach towel (sunbathing, relaxing, napping, etc).2024-10-18: Added breast movement to the "pee walk" animation. Added penis and breast movement overrides for relaxing on the bed animations.2024-09-13: Updated showering animations to add breast movement and improve penis movement. While adding breast movement to these animations, I discovered a few different techniques I could use to create my overrides with more bounce, so I re-did the penis/testicle movement for the showering animations. I plan to use these techniques on new animation overrides going forward, as well as improving my existing overrides as part of future updates. I've added a gif showing a brief comparison between my original override (on the left) and the override created with the new techniques (on the right).2024-07-29: Fixed an error causing jogging breast animations not to show up correctly in game.2024-07-27: Updated jogging animations to include breast movement. Note: clothing tops can deform with breast movement, so I recommend using my BetterBoobs add-on with SimMotion. BetterBoobs is available from the Clothing Collection page.2024-06-25: Created the masterpost. Added overrides for double/single bed napping interactions (as seen in the post header image).2021-05-21: Added overrides for female walkstyles.2021-05-14: Added overrides for multiple sitting idles, seated "listen" animations, "watch tv" animations and basic seated postures.2021-04-26: Added overrides for sun loungers.2021-04-13: Added overrides for stair animations.2021-03-23: Added overrides for jogging and basic bathroom hygiene functions (including using the shower, bathtub, toilet, and the "needs to pee" walkstyle).2021-03-13: Added overrides for male walkstyles.2021-03-09: Launched SimMotion.
