Stand Still in CAS (15.01.2024)  

Sims do not move in CAS. Including mermaids and vampires. 

Shimrod Version
This is an override mode that prevents your Sims from playing idle animations while you are creating or editing them in CAS. No more looking side to side, heel rolls, weight shifts, etc. For all genders, ages and the occult! The mod also stops the reaction when you go into a stylized view, or make a Sim Fit or Fat. An alternate version, Occults Only Version, disables only occult animations (vampire growls, mermaids giggle, cast spells) so Sims will move and react normally.

Your Sims will still animate when randomizing, choosing walking styles, choosing traits and desires, changing ages, and adjusting the voice slider. The voice slider and randomizer use the same settings, so if you want a sim to move with the voice slider, it should stay the same. The eyes will also move and blink like in detail edit mode, since this animation is now the default for all other animations (except for mermaids, which use their own animation). There are two things to be aware of that I can't fix (yet): Sims recline a bit due to how the new animation clip works, and that male elders move their feet when switching styles. The latter seems to be related to how elders usually stand in CAS, but I'm not 100% sure. future update, which I think would be for a more natural animation by default, but I should look into that later, along with pets. Both versions are compatible with any combination of packages.

Shooksims Version
Someone asked for an update to this Shooksims version, here it is! This stops all idle animations for all groups just like the Shimrod version, but uses a custom pose and allows Sims to react when selecting Styled Looks and setting Fit or Fat. Your Sims won't blink like Shimrod either, but they will still animate when randomizing, choosing walking styles, choosing traits and desires, changing ages, and adjusting the voice slider. I may add blocks to the "Stylized Looks" and "Fit/Fat Man" animation later if it's interesting enough. It is compatible with any combination of packages.
