Ok, I had a look at your project. Im not really sure what you are after with the “weeping angel” effect, but im guessing you want them to look at you only if you look away? The problem you are having is how you use the RInterpTo node. It works now so have a look at the blueprint and note the changes I made. There are even better, more optimized ways of doing it, but this will do for now. Cheers!
