Good, I want to know that height approximately it is necessary to put in the modifying of heights have been reading the manual and it puts: Modifier of Height - Allows to determining to what height the personage is going to fly when one displaces from a point of reference to other one. If the boat is flying to a very low height it is necessary to define a positive number, if it is flying very highly is necessary to change to a negative number. I have been trying ... putting-50,-80,-100 the problem is that it me does not appear this numeration in the square That I can do?? Thank you
