Tried to make scrolling text using shaders and text mesh, video below (results at 59 mins -> ) Shader Sources:(one for text mesh, one for UI RawImage that displays camera view as rendertexture)

Color Cycling Shader test, because. Shader Source:https://github.com/UnityCommunity/UnityLibrary/blob/master/Assets/Shaders/2D/Effects/ColorCycle.shader How it works?Gray color value is used to pick color from the gradient, if gray texture pixel is 0.5, then you get that turquoise color from gradient texture.
