create flashing light effect for ambulance
Hello, I'm working on a traffic game (3D). And I need to implement ambulance siren light effect. I have read other posts on forum but no one served the purpose. They all tend to discuss the switching lights on and off pattern and scripting side of the problem. I am having issues with the lights setup in the unity editor.
What I have tested:
used self Illumination shader on light modal and put a point light inside it.
used glass shaders found on asset store, for light modal and putting point light in it.
tried rotating a spot light on the ambulance roof.
used Halo effect
particle system that emits only one particle and use default-particle material. I'm changing the 'size over life time' property to mimic light spreading in environment.

Rotating Spot Light link: http://www.ytpak.com/?component=video&task=view&id=AKJZVzkX4d8
What is the main issue in all approaches:
light becomes visible only when casted on a mesh. I want the light to go out in environment (in the air).
I have also tried using a quad with default-particle material and casted light on it with a spot light to show light spreading in air, but it doesn't produce a 3D effect.
What I actually need:
Flashing ambulance lights which produce 3d effect and is easily visible in the traffic of around 10-15 other vehicles from at least 50 units above the ground.
It would be very grateful if someone could help me find a better solution.
it's not exactly clear to me what you mean with 3d light effect. I mean, it sounds like you want some kind of halo or lens flare effect with your lights?
do you have an example image of the effect you want? that might help.
I think you need a lightcone. it`s basically just a simple cone to simulate lightshafts.
In this post you can even find a working example. http://forum.unity3d.com/threads/how-to-create-a-light-cone-or-shaft-of-light.2660/
yes this is close to my needs. so, I need to create star likes transparent meshes to get the effect as shown it the images shown in the above comment. Thanks for referring to volumetric light concept.
