First of all I need to give you an idea of how much of a newb i am... I started a Digital graphics and animation class this year and was supposed to go through the whole adobe creative suite then move on to maya second semester... I finished the creative suite in about 2 weeks and had nothing to do so the teacher decided to move me up the the second level class, which meant iwas gunna spend a whole year in maya and have to keep up with the kids who had already had a semester of experience in maya. I had never used maya until 3 weeks ago and i had toget some quick tips from a friend of mine on how to make frames to make simple animations to keep my grade up ( I already know more than the teacher so she is not much help) I dont know any technical terms but I can learn really really fast thats about it.

So... on with the question... I have been working on an animation and I need an object i have created to be there but it just needs to appear in fram 60 and dissapear in frame 65, so far i have just saved screens of it there and then before and after i scale it down to almost nothing but I realize when i start making more complex movies having the extra clutter will be really really bad so did anyone know how to make objects appear and dissapear like that??
