Insert Edge Loop not displaying
I'm busy with the Chef Ramsay tut and I've just about finished the jacket and trousers. For some reason I have lost all visual feedback on the "Insert Edge Loop" tool. Usually, when inserting an edge loop, I'd have a dotted green line moving on the edge I'm inserting on, though this is missing now for some reason. All I get is the knife type pointer and then nothing until I finish the command, where I then see the new edge loop.
So, select Insert Edge Loop, click on edge. Expect to see dotted line move with mouse as I move on the edge...It's not there!
This only happens in this one scene. If I start a new scene the tool functions as usual. Maybe a setting has gone ape?
Any help appreciated. I'm on 2009 SP1.
