I couldn't find a thread dealing with this, so I hope I'm not spinning a broken record. All I know is, I'm getting very tired of this error message. The mesh in question has been assigned a MR subdivision approximation (the length/distance/angle variety). I suspect it has something to do with it. Would anybody know how to rectify this?
Also, in a related matter, where can I find the approximation node (say I want to delete it entirely)? I read somewhere that it can only be found in the hypergraph, but it doesn't appear to be there.
