Okay, so frame 1, move gradient all the way to the left. Done.

Make new frame, frame 2, move gradient all the way to the right. done.

Problem is, whatever I edit in frame 2, it changes in frame 1, so i can't tween and have it do all that shit.

Really freakin annoying. zZz

Make sure you're only moving the gradient layer

>.< i'm only moving the gradient layer...

I remember I had the very same problem when I got into ps... can't remember how i fixed it exactly, try right clicking on the frames and playing with a couple of settings given

I may have read it wrong but if both frames are getting changed then maybe you need to click the little eye next to the layer before you make the second layer.

... why did i forget about the layer visibility o.o

still having this problem. zZz

u have to click the layer eye before you tween it

I've had this problem before and I think there is a setting for it but I believe I solved it by creating a third frame and doing the different things with the 2nd and 3rd frames then deleting the 2nd frame when I was finished
