Line/Ray Drawing or Change Pawn's Color and over head label

[projecttemp]

Hi, i got a mod that i want to draw some visual effects for, the effect i am thinking is line a sort of energy line or some sort of aura around the character. However i don't know how to draw lines in Rimworld, the thing i stumble upon is the LineRenderer, but it must be attach to a gameobject which i don't seems to have access to, any other way to do this? Maybe using drawlinker?

For aura, i was thinking of maybe changing the entire pawn's color(including apparel), like a color filter on Pawn and also drawing a label on top of the pawn's head. This only applied when the pawn is selected or is drafted.
