I'm trying to blacken and fade the edges of the screen inwards, but it looks really messy outside of the editor.
Firstly I created a rectangle and generated a Movie Clip symbol. I then added the Blur filter, quality high, x and y both 50px.
It looks hideous and stretched. Is there a way to fix it or would I have to create a separate symbol for each side of the screen? Even then, I wouldn't know how to anchor them and stop them stretching - I'm new at flash pro.
Can you share an example file using Box, Dropbox, or Google Drive so it's easier to understand your issue?
If you are using a rectangle with no fill, you will probably get a better result if you increase the line width of the rectangle and then adjust the blur x and y to suit.
