Advice on where to begin creating these type of materials in unreal (ref images provided)

I’m tasked with creating many new materials for our avatar in game. I have a pinterest page with styles we like and i’d like to get cracking on these. i wanted to ask the community first on how they might approach some of these materials. maybe nodes to use to achieve these looks, things to avoid…just whatever info i can. i always want to get better with the shader tree in unreal and i’m hoping to get some help on these.

Look #1

This to me looks like some type of procedural noise mapped to a gradient? seems simple enough? to get the mapping to work like this on the body i’m guessing is some type of tri planar, i’m hoping that i can have the noise animate so the colors will change on the character?

ANY advice on creating something like this would be amazing.

this SEEMS simple enough…i’d have no idea where to being though…i’d hope i could have a slight distortion to the lines so it looks animated, i’d also like to have the lines moving through the body is possible?

Look 3

I would love to have some type of material like below where the lines run up the character, ideally using some type of…world mapping? i wouldn’t want this to be associated with the uvs if that makes sense.

Look 4

this is i like, i’m hoping this is also possible?

I would be thrilled if anyone can point me in any directions that may help me in creating these type of materials. thanks in advance!

Look2 I think I got it by mistake while playing with an outline shader, I divided SceneDepth by to much and then outline each depth step.
Look3 I saw something similar yesterday, Hologram Tree in Chapter 04 of Unreal-Engine-4-Shaders-and-Effects-Cookbook ( GitHub - PacktPublishing/Unreal-Engine-4-Shaders-and-Effects-Cookbook: Unreal Engine 4 Shaders and Eff ).
