Specular glow??

[Ergi]

What about rendering the spec pass separately, blooming it (dilate, blur) and then comping it on top. (and then maybe you can screen a little noise/scratches on the broad spec so its not perfectly smooth ). Then on top of that goes the hot spec....? So now you can even color them separately. Drop a tiny shadow from one spec on top of the other maybe gives a little extra depth ?

aww it hurts cheating so much :scream:

cant help you in XSI though, havent used it much

[Ian Jones]

Say.. what? why would there be a shadow between the specular reflection and the bloom?

[Caligo]

Thanks ergi, I'll give that a try. That'll give me a lot of control over it if I use it. I'm not really sure about the shadow, could you explain that one? Isn't the glow an illusion anyway, caused by the eye or by the lens of the camera if it's a photo?

[Ergi]

mmm..dont know thats why i put a question mark behing it. Guess its worth a try. Simulate a bit of depth (as if the bloom is on a paint layer further down) or maybe i was just getting carried away :shrug:

As a rule of thumb it's ALWAYS a good idea to do any effects that are lens, film or retina based ie glows in the composite. Renderers such as PRMan don't have glows built in as standard for this very reason (though if you are particularly sick you can write nasty looking glows in RSL). Anyhow, if it glows/flares/blooms/chromatically aberates blah di blah, do it in the comp.

Caligo, i must have misunderstood but i thought you were talking about a secondary spec (broader and softer) due te the paint layers and imperfections of surface,...not a lens glow from camera. All suggestions though still remain valid

"if it glows/flares/blooms/chromatically aberates blah di blah, do it in the comp"

amen to that

I know there's some way to turn on a lighting star or bloom or whatever it's called in Maya, but I thought it was in the light itself and I couldn't find it... was it in the camera settings, or in the render globals or something?

[redfuzz]

in maya, under special effects for the shader of the car, turn up glow intensity. Now your whole car glows.
Find shaderGlow1 in the materials tab of te the hypershade, play with the glow setting to your hearts desire. Using a higher threshhold value will tell the glow post process to only glow the brightest spot s of the render, ie. the spec highlights. Glow will flicker if auto exposure is turned on.
