Quick & Easy Alpha Mattes in TouchDesigner - Tutorial

A common scenario for developers and artists is that you'll receive an asset that you wish had an alpha channel. This might be on a project where the content team sends you an asset that should have an alpha channel but doesn't. Or this could be an asset you have that you want to composite on top of your content. With Channel Mix TOP, you can quickly and easily create an alpha mask from almost any type of content and further process it with Blur TOPs and Threshold TOPs. This is a trick you'll end up using in your daily workflows.
