Stores I personally use are listed below. Except for the rare couples dance animation, I only buy copy versions. Unless a store sells copy animations, I won’t use them or recommend them. Feel free to suggest others in comments!
First stores I recommend for new choreographers:
Dances – Abranimations
Smooth transitions into and out of, can be used to link animations, low cost compared to other dance animation stores, most packs include mirror dance animations, expressive, great variety and overall quality, all animations are copy.
Animations – Kuso
Excellent variety of animations from standard to unique, make sure to check out all 4 animations rooms – especially the RP room. Low cost – 10L for non-bento, 20L for bento. All animations are copy. Watch buying packs – they may include some duplicates to others, such as the swim animation.
Poses – Nantra
Excellent variety, frequent sales, store credit is given for each purchase, mirror animations available for almost every single animation – purchased separately or included in the animation pack
Don’t forget! You can easily copy animations from furniture and other objects if you have copy rights! Cars, couches, props, ballet barres, etc – copy the animations to your inventory and use them in your dances.
