I've created a rectangle by using the pen tool, then applied a stroke to it. I've then added "trim paths" and the end value at 0seconds is 0% and then at 5 seconds its at 100% however the line appears from the wrong side of the screen, basically it's reversed, yet the reverse path symbol is not ticked.
The line is meant to appear from left to right of the screen with a 2px stroke, which will then have a mask applied to show a large black box appear from this line and fill the rest of the screen up.
Anyone able to help me at all?
If you animated the start then animate the end. Simple as that.
