Shadow Mask not Exporting

[simonono]

I'm trying to export my animation as .mp4 file, but there is a mask that will not export. The others masks I have made are fine and are all visible in the exported version. Not sure what to do about it.

Hi mate,

It really is impossible to tell based on just the results. Who knows... It's unclear how you've set your files up and what goes on in there.

But since it shows in the program correctly you can try to render your animation as a PNG sequence. If that exports fine, you don't need to worry.
