I posted this in the wrong community at first, but my problem is that I'm having trouble with exporting my animation to a video--when I export, the masks I have created disappear and you can see the whole image again. I'm not sure what I'm doing wrong? I attached two screenshots--the masked one is how it looks on my stage in Animate, and the unmasked one is how it looks after I export it.
Please, edit your post and use the image button at the top to add the images.
There is a bug with the forum and attachments don't work, so I can't see them.
Also, it probably would be best if you share some portion of your FLA file for inspection. It is usually difficult to tell what a problem with a mask may be by just looking at the results. You will have to upload the FLA to a file sharing service such as google drive and post a link here.
