Oh I just realized that when I tried to download the shader individually from Github I downloaded a link to the page. I just downloaded their whole gitHub master file it works.
However, I imagine that I will probably have other questions as I go. I wonder if we can keep this thread going for questions.
Eventually I want to write a shader that will basically act like a blend(MULTIPLY) filter on video. I’ve gotten that kind of code running without a shader but it really puts a strain on my computer. This may be some time later in the future. I’d like to get a firmer grasp on the basics.
Thanks for your help.
