So i wanted to erase the second replays from the beginning to the right moment for not have them to interfere with the firsts views, but when i select one and i choose cut nothing happens
Aldherrian, I didn't really understand Tuta's reply regarding the cut tool, so maybe he will provide more information. Every time I try to use it, I can't get anything to happen either.
Other than that, I don't know of a way to shorten a replay. The only things you can do are:
1) Use a shorter replay--either start the car at a later point in the track (in the editor test mode) and hit "S" at any point to save the replay, or
2) Build a short fake/imitation version of that part of the track, with maybe a booster at the start to get the right speed, and make your replay on that track, or
3) Just make the ghost start at a later time. Click on a ghost and change the numbers in the "start offset" box. These numbers are seconds, and you can make the value negative or positive. By changing the start offset number, the ghost will "start" at any point you wish.
