Why is the material distorted when i animate the mesh?

If I animate the mesh, the material gets distorted. Why is this happening?

For example:

If you have a procedural texture (like noise) which you'd like to stick to the object you need to add a Pin Material Tag (former Stick Texture Tag) to the mesh, or export a reference object and use the Pref space in the shader, as described here: https://docs.arnoldrenderer.com/display/A5AFCUG/Export+Parameters#ExportParameters-Referenceobject

Otherwise it could be maybe an animation/simulation setting to prevent the UVs swimming, not sure.
