Hi, I am desperately looking for the Beziér masking plugin. I use Vegas Pro 15 and my program language is in German. Supposedly the plugin is also called "Beziér Maskierung" in my language, but I can't find any trace of the plugin. Maybe you know more...
It's been a while, but I don't think the plugin was introduced until Vegas Pro 17
I've just checked my older Vegas Pro installations (in English). There was no VEGAS Bézier Masking FX in Vegas Pro 15, it's first appearance being in Vegas Pro 16.
In Vegas Pro 15's user manual (Help/Contents and Index - or F1), there is a section starting on page 166 titled "Creating a Bézier mask" which you might want to refer to and see if the masking available in Vegas Pro 15 will do what you are seeking to do.
My mistake! I had gotten Vegas 18 at some point and now had 15 installed xD I knew I had used the plugin at some point. Thank you!
