@djaydino - I have the laser setup, what I wanted was for the laser to follow the contour of the terrain/ramps, as is if it hits a hill/ramp it just stops at the hit point, so basically have a line that follows the y coordinate of the terrain... projectors seem to be the answer but I changing the xscale of the projectors texture doesn't seem work.
@ tcmeric - looks cool, but can't find any forum posts regarding the asset or a way to get in touch with the developer
thanks
