I realize I’m responding to 5 year old thread, but I’m curious. Could you explain what is happening between Effector’s color mode, the Colorizer, and the Color Shader? What’s the relationship that drives it?
I came across this thread today, and your expression works like a charm. I’m curious if there’s a way to achieve a similar effect, when there is no camera in the scene. If the line itself moves in Z space (not the camera) could the stroke remain constant?
