Hi there,
To start off with I am very new to shader programming. However lately I have been familiarizing myself with Amplify Shader Editor. One of the shaders I found online which I have been using is used to make a basic Gaussian blur. Which until now has worked just fine for me. However I'm looking to turn it into a Shader Function so that I can customize it more and expand upon it.
I am looking for some assistance or prehaps someone can point me in the right direction to which nodes I should be using.
Shader in question: HERE
Any help would be great! Cheers, Tristan
