I haven't touched the modifiers and am thoroughly swamped by edges. I really think people who aren't getting them must be a result of the difficulty, pitch and weather conditions or their batting style - by that I mean what shots the user attempts to play, not the animations. I'm also only using the pitch marker - have tried without too - and so my timing and judgement of length is not always going to be great which will create more edges 'naturally' rather than playing around with the physics modifiers.
100% agree. I edge it about as much as I'd expect. Like you I just use the pitch marker as well. Could be something to do with that ?
