Welcome back to an actual video tutorial!

I'll address opacity mapping in this video tutorial in response to a recent thread at Autodesk's Area forums.

Often, when applying opacity maps you'll notice that the edges of objects that have the map applied are not necessarily fully transparent.  I'll explain why this occurs and the simple steps you need to apply to correct the problem.  Opacity mapping is a powerful tool for simulating geometry by making certain areas disappear or appear transparent.

Download the file called Opacity_map.zip from the FTP site and extract it to your hard drive.  Double-click on the HTML file to open the video in your browser.

Please note that I am now using Camtasia 5.0 which works slightly differently than previous versions.  Notify me immediately if you have troubles opening or playing video.

Good luck and have fun
Ted
