Hello, Everyone. I am fairly new to Unreal and haven't ever really used the Material Function node, but recently came across this post on building a custom fabric shader. So I thought it was worth looking into given its results, however I am stuck on page 17. I have all the nodes except for the one labeled "LigthtVector"…
I am not sure if that would work in your case, but what I did when I needed the LightVector a while ago was having a blueprint which basically took the direction vector of my directional light (aka the main light source) and put it into my shader through a material parameter collection, maybe you could try that? I don't…
