After Effects trim path trouble

[alexandraw66449875]

Hi, I have a little question. I wanted to do trim path on a regular square, but it doesn't start/end from top to bottom, it starts from bottom right corner to top left corner. I'm sure it's not a big deal, but for the life of me I can't figure it out. What am I doing wrong here?

Adjust the Offset till the trim starts where you want it:

Trim patch starts at the first vertex. You can either use the Layer Mask and Shape tools to set the first vertex or you can use the offset to move the start.

Show us what are you doing in the timeline Trim Paths options.

My guess here is that you're trying to employ 'trim paths' to trim a square with a fill.

Trim paths isn't designed for that. It's designed to trim 'paths' - eg 'strokes', not filled shapes.
