I have started a new series of videos on my YouTube channel aimed at helping artists learn to create shaders in the Material Editor. The videos start with the basics and will build up to more complex techniques as we go along. There are 4 videos available so far, but I’ll be releasing a new one every Thursday.
Check it out!
Thanks. I’ll save 'em to watch later. There’s not much in terms of basics on youtube, so it’s a nice beginning. Lots of tutorials presume prior knowledge of certain expressions and other nodes, so it’d be really helpful to cover those thoroughly. One I think of is exactly what math expressions do in particular connections / cases. I have a difficult time understanding when to use multiply, linear interpolate, add, subtract, 1-x, and divide nodes, at least when I’m trying something on my own and not according to a tutorial that’s about a specific effect.
That’s a really good point. I’ll do my best to explain what the nodes are doing and how the math is working as I go along. In Episode #4, I go into what multiply does with UV coordinates (it scales them up and down) and what add does (it scrolls them). You can see that one here: Distortion Shader - UE4 Materials 101 - Episode 4 - YouTube. In the next episode that’s coming out this Thursday, I’m going go over flipbook animation and explain the math behind that. If there’s anything you want to know more about, I’d be happy to answer any questions that you post.
