Is it possible to make a object shine? Let’s say you wanna make a laser beam and you just wanna see the laser not the floor or anything else, just the beam. Is that possible?

If you go in to the material settings, there will be a slider labeled emit. This controls the amount of aditional light the specific object recieves (or something like that). The light is will not affect any other objects (aka a neon tube) unless you use the yafray renderer.

Thanks! Let’s say I wan’t it to light up the enviroment.

Put a lamp inside the laser beam. If the laser beam is moving, then select the lamp, then select the beam, then press CNTRL + P to parent.

I’ve heard of something called radiosity. What’s that?
