I wanna know wrong with my animation?!

如图所示，Sims的臀部在动画过程中消失了。请问是什么原因造成的，谁能告诉我？谢谢！?

If this is only happening during the animation, it is because the animation is introducing an asset that you do not have installed. This could be an asset the animation came with or it could be you have a clothing override for this specific scenario that you no longer have installed. If it is the former, fix the animation. If it is the latter, open CAS on the character mid animation to see what they are wearing, remove it and click check mark to reload into the scene with the asset removed. Also, clear your cache. That's not normal.
