Hi

This is a weird question, I guess, but do you guys know of a site that has a large collection/overview of custom animations? I'm not looking for anything specific, but I noticed that the cc overview sites I know only have 1 or 2 animations. I just like browsing and clicking whatever catches my interest. So do you guys know some sites that have more animations?

There are loads of mods that offer custom animations. Just a couple for examples:
icarus_allsorts has offers many, many mods that have custom animations. See them Here On This Page
No Stretch Children Can Series by kaper

All available mods here at MTS are listed On This Page
NRaas has a listing of Other Mods Here , many of which, have custom animations.

Does this help you or am I not understanding your question?

I was thinking more about animations for the animation player, but these actually do help me

My Sims 3 blog did as I recall. But nothing new has been added since Dec 2016. http://mysims3blog.blogspot.com/

AFAIK, most, if not all, of the mods by icarus_allsorts consist of custom interactions that trigger EA animations. The animations themselves are not custom.

If you want a pretty funny example of his reusing already existing animations, take a look at what happens with his toilet stall Woohooer add-on module (from NRaas, not here, when he was wearing his hat as an NRaas developer). I won't give it away, but nearly fell out of my chair laughing at the animations he selected to use -- the not so obvious ones I mean. Since then I've learned not to watch very closely when that one gets invoked.
