Ok im very used to using lights to illuminate your scene and pretty much which ones to use when and what ones to use shadows with etc… however I need to know how to make a real light. What i need to do is create a flashing beacon that you get on aircraft and I am unsure on the technique on how to do this. I know how to keyframe the ights to come on and off so that isn’t the problem its just finding out how to create a real lightbulb that i am having trouble with
Do you want to have the effect of having an actual light bulb object, which i think is what you're getting at?
The way I've dont this before is to create the geometry of the light.. say a light bulb with a fillament inside. Then you can place your point light right in the centre and it will seem as if the light comes from the fillament.
To help the effect you could make the fillament have 'self illumination' -by turning it on in the material editor. This will make it glow. You could also switch on the Volume Light in the environment/effect settings, and choose your light. this creates a atmospheric glow around the light.
There is also a way to make light emit from the surface of geometry which may help.
