the physics shape is being overstretched when moving.物理学形状在移动时被过度拉伸。

Adding a physical form to the character’s breast, an error occurs when running, and the physics shape is overstretched when moving.

I added physics to the character’s breasts to simulate it.
I locked all the constraints of the physical form, but the wrong motion still occurred when running in the world, overstretching the physical body.
I don’t want the character’s breasts to be stretched like plasticine when moving, I want the physical form of the breasts to move normally in the world, does anyone know how I can solve this problem?
Please help me, thanks.

给角色乳房添加物理形体,运行时出现错误,物理学形状在移动时被过度拉伸。

我给角色的乳房添加了物理形体进行模拟。
我将物理形体的约束全部锁定了,但在世界中运行时依然会出现错误的运动,将物理形体过度拉伸。
我不想让角色的乳房在移动的时候被拉伸得像块橡皮泥一样,我想让乳房的物理形体能在世界中正常运动,有人知道我该怎么解决这个问题吗?
请帮帮我,谢谢。
