Visible Light Glow

Recommended Posts

I'm new to 3DS Max 7 and I'm trying to acheive the exterior white glow lighting effect seen so much throughout the gallery. I'm also trying to get an internal ambient effect as well.

 

I read Montree's tutorials but based on them could not achieve the same effects - I'm not sure if it was the render engines, or what.

 

I simple need the right information on how to achieve this effect.

 

I've posted the URL to the image effect I'm writing about...

Any help would be greatly appreciated.

 

Thanks

Two ways to do it:

 

1. in photoshop - just blur a white shape over the place you want the glow

2. Mental Ray's glow shader, but I don't use Mental Ray

 

You could also do it in post inside of Max, look up 'glow' in the help menu. I've never seen it used like this, although it's been suggested by many.

Specular bloom. There's a script that comes with Max that can do it (the name of the script eludes me right now). Or you can make it in post (IE Photoshop). Or you can use the glare shader in Mental Ray. For the MR process, there are example scenes on my website (max6 and max7 files).

Neil Blevins has info on a technique here as well:

And there are probably other threads on specular bloom around here.

Scott - we'll, if you find a version that is not Mental Ray (as Jeff notes more specifically), not Photoshop, and not a post process inside of Max, then I'd sure like to know.

 

Do a search, you'll see this has been discussed numerous times on several forums.

 

If it's not listed in the tutorial, how can you be sure how it was done?

You can cheat it by using the "glow" effect - mental ray is not needed.

 

To recreate the scene you showed - create 2 boxes and place them over the glass, apply any colour but make it 0 opacity (make sure you ignore these boxes in your lighting peramaters too). These boxes represent the glass where the effect with take place. For the boxes properties, make them Object channel ID - 1 (or whatever - just remember that number)

 

Under effects, choose lens effects and glow.In options tabs, make sure the object ID corresponds with the Object channel # (ie 1.). In parameters, make sure both radial colours are white (if you are even more daring place a noise map - to give the glow some realism) and make the size 0.01 and Intesity about 70. Play with these to number to achieve different brightnessess.

I DL'd the file. Thanks so much Jeff. I studied it and when it rendered it duplicated the effect perfectly. For some reason MR is doing it just fine while I could not get Radiosity to render light bounces at all. MR is going to have to do it for me.

 

Thanks again
