Media Encoder ignoring track matte when exporting AE composition.
Hey all,
I'm having the issue described in the title. I have an animation that uses a track matte to mask everything in a particular shape. If I render this composition directly from AE it exports OK. But if I do it through Media Encoder said matte is ignored.
- How it should look (and how it looks rendered directly from AE):

- How it renders with Media Encoder:

I could use the lossless export from AE, place it in Premiere and render it OK from there with the specs I need, but the extra step is time consuming and annoying, specially as I need multiple version exported.
I'm using both After Effects CC 2018 and Media Encoder CC 2018 on Windows.
Any help is greatly appreciated.
EDIT: Forgot to mention, the whole animation is a lower third to be transmited on live TV, so it uses an alpha channel. I have this usue with both .mov and .mxf exports and NOT with PNG sequence exports.
Thanks!
