Custom Fabric Shader In Unreal

Three65

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" at the start. I was wondering if someone could offer me some insight on what node this is. Also I may need some help pulling all of this together into a material. A lot of what is in this tutorial is over my head when it comes to Unreal.

I think you should just use the standard cloth shader instead.

Well if you can point me in the direction of a tutorial that will help me achieve a realistic Satin and Velvet Material inside of Unreal with the Standard Cloth Shader I would like to have a look at it.

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 think there is a built in "Get LightVector node" in Unreal.

Fuzzy shading node should get you pretty close for velvet at the very least!

Use blueprint to feed it a light source. Youll only have one light on the model though. 

You should be using a dual aniso lighting model for satin and ashikhmin for velvet. I believe the cloth shader in UE4 is ashikhmin.
