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?
If a setting has gone off track reset the tool in the tool options or export the object as an obj, then bring it in again, might be something as easy as that. Maya has that tendency to work in this manner
