Thank you for looking in to my problem. I am having an issue applying shape keys or loc roc to my scene. I am trying to animate one of the tentacles i have or just have shape keys move the mesh so that it can look like it's floating but when ever I apply loc roc or create a shape key nothing happens. I've been using a curve modifier to move the mesh around. Is this why I cannot animate?
I've attached a link to the blend file.
