Welcome aboard!

Yes, you can remove a mesh (mesh.dispose() if you want to remove the mesh from the scene or mesh.setEnabled(false) if you simply want to hide it) and add a new one.

I think the mesh section of the doc should help you: Meshes | Babylon.js Documentation

Maybe you can provide a playground so that we can help with some code.

I want to replace shirt with box mesh

You did not say it was animated…

It will be quite more difficult because you would need that the cube have the same bones than the existing torso for the animation to work as expected.

You can try to use attachToBone so that the box follows the same animation than the torso, but it has some limits (also, you need to tweak the box position and scaling to match the model):

@Evgeni_Popov I have a mesh with same bones as shirt then how to replace the shirt with that mesh.can you share code snippet

Simply hide/remove the old mesh and parent the new mesh to the same parent than the old mesh. You should also assign the same skeleton:

newMesh.parent = oldMesh.parent;
newMesh.skeleton = oldMesh.skeleton;
oldMesh.setEnabled(false);
newMesh.setEnabled(true);

@Evgeni_Popov Mesh attached to avatar but animations are not working properly.newmesh has same bones and animations as the oldmesh.

I guess we will need a PG to be able to help more.
