    Issue still present in 2020.1 version. Analysis: the Cloth vertex deformation code seems to constantly recalculate the SkinnedMeshRenderer bounds and it messes it up.

    Fix: add this script to your SkinnedMeshRenderer object or higher in hierarchy.

    using UnityEngine;

    public class FixClothBounds : MonoBehaviour {

    private SkinnedMeshRenderer[] Renderers;

    void Awake() {
    this.Renderers = this.gameObject.GetComponentsInChildren<SkinnedMeshRenderer>();

    void OnRenderObject () {
    foreach (SkinnedMeshRenderer smr in this.Renderers) {
    smr.localBounds = new Bounds(, new Vector3(10f, 0.2f, 10f)); // Paste your meshes real bounds here

    Issue still occurs in 2019.4.0 and 2019.4.3. Is there plan to integrate fix to next LTS release?

    Hi, thanks a lot for sharing this with me. I am starting a new startup and was reading a business plan on website and really liked it a lot. I will use this plan to make my startup successful.

    Still bugged for me in 2019.4.0 ... >_<

    It works a bit better if my root gameobject (not the root for the bones) scale is (1, 1, 1), but in that case some normals get messed up and the skinnedmesh still disappears when it shouldn't, although less obviously.

    I'm using Unity 2019.3.0f3 and I think I may have found a solution, at least for simple cloth like a flag drooping down. I made a joint chain for a simple plane in maya, bind the plane to the joints, then export. Afterwards I put the binded plane in my scene and on Skinned Mesh Renderer component, I ticked Update When Offscreen to True. I'm not sure about other complicated meshes, but it seems having a joint hierarchy worked for me.
