Hi i have a gltf model with a flag and a sail animated using shapekeys that i want to replicate many times.  
It is possibile to do this?  
Can i use InstancedMesh in combination with morphTargetInfluences and morphTargetDictionary?  
I have to play exactly the same animation for each instance.  
If it can’t be done with InstancedMesh then can i do it in other ways?

Thanks 🙂

So InstancedMesh with morph attributes is not supported ☹

Anyway I have made a flag waving animation using ShaderMaterial but i need some help.

For the flag i would like to know how i can access the instance id in the fragment shader to be able to set a diffrent texture for diffrent instances.

For the sail i need to know how i can pin the 4 corner vertices of a plane and moving only the others.

To pin the corners of the plane i have tried this:

```javascript
void main()	{
    vInstanceColor = instanceColor;
    float theta = sin( time + position.x ) * factor;
    vec3 transformed = position;
  
    transformed.z = theta;
    if(uv.x==0.0 && uv.y==0.0) {
    transformed.z = transformed.z*uv.y*uv.x;
    }
    if(uv.x==0.0 && uv.y==1.0) {
      transformed.z = transformed.z*uv.y*uv.x;
    }
    if(uv.x==1.0 && uv.y==0.0) {
      transformed.z = transformed.z*uv.y*uv.x;
    }
    if(uv.x==1.0 && uv.y==1.0) {
      transformed.z = transformed.z*uv.y*uv.x;
    }
    

    vUv = uv;
    gl_Position = projectionMatrix * modelViewMatrix * instanceMatrix *vec4(transformed, 1.);
  }

```

The corner with uv (1,1) is still moves ☹
