How to create a halo // Archive: Tech Forum 1  |   Order by default Post by louisbyrne // Sep 21, 2006, 6:57am louisbyrne Total Posts: 8 Has anyone tryied to render a halo? Trying to make a halo effect on rings to create a cool science fiction scene. I tried to use pyrocluster to turn the rings into some kind of gas, but did not work. I am looking to turn the rings into trasparent see-through light rings. Any tips are welcome.

Do you have an example of the kind of effect you are going for? It would help to see what you're trying to accomplish.

Thanks.http://www.randomdrifts.com/img/aliens.jpg Post by Chester Desmond // Sep 22, 2006, 4:46am Chester Desmond Total Posts: 323 here's a couple ideas that might work...using the Edge series of shaders from CK Game Factory in both pics... 1. Using material light 2. Torus surrounded by a slightly enlarged copy ... it looks a little too glassy in my pic but that could be adjusted... You might also look into Megaglow postprocess shader from CK.. Post by Bobbins // Sep 22, 2006, 4:51am Bobbins Total Posts: 506 One method of doing this is to make a copy of the object you want a 'halo' around, scale it a little larger then apply a suitable transparency shader with reasonable ambiance/luminance values - any 'glow' type shader will work nicely. This is the standard trick used for creating atmospheres around planets and so on. The scaling of the 'glow' object should be along the vertex normals which is quite easy with simple shapes like cubes and cylinders, but for more complex geometry the tS scale won't work and some point editing may be needed (make a torus, copy it then scale the copy to see what I mean).

Thanks for your suggestions http://www.randomdrifts.com/img/halo.jpg :jumpy:
