Help My shirt

Ok. Now I see the problem in this second pic: you're using a SkinnedMeshRenderer, instead of a regular MeshRenderer.

For skinned meshes, things work a bit differently: all particles start out completely animation-driven (fixed), and you have to unfix the parts that you want to simulate. See:

If you don't want to blend animation and simulation for your shirt, then you should not use a SkinnedMeshRenderer. Use a MeshRenderer/MeshFilter combo instead. Note that if your mesh contains skinning/animation information, Unity will automatically add a SkinnedMeshRenderer instead. See:
https://docs.unity3d.com/Manual/class-MeshFilter.html

Sorry, I cannot solve the problem. It does not work well. I used  MeshRenderer. What is wrong?
