looking for linear lighting beam for concealed light behind joinery
What exactly are you looking for? Do you want to know how to model these things? Do you have a photo of the sort of thing you are looking for?
What version of SketchUp are you really using? Your forum prpofile says SketchUp for Schools 2024. SketchUp for Schools is a web based version for school children. Is that what you are using? Your username implies you are using this for a business and wouldn’t be a school-aged child. If so, what kind of subscription do you have? Or are you using a cracked version? This information will tell us what kind of tools you have available.
Also please realize that SketchUp’s shader only handles lighting from two source: the camera position or the sun. Unless you are adding a light that will be recognized by some real renderer, all you will get is the geometry of the light, not its illumination.
Hi your looking to give some give an idea (impression) of LED light around the perimeter of your joinery work?
