Computer Lite Glow

Hi,

Thank you so much for taking the time to respond.

I don't have a clip available -- but we would like to create the blinking lights of a bank of computer servers.

I was able to achieve a glow effect with EI's glow feature, but Camera crashes?

I've never used the feature you describe.  I will try it.

Could you tell me where "you assign geometry to be  light emitting?"

Thanks, again for the time and insight.

Do you really need that the blinking LEDs illuminate the environment and do you have another main source for the lighting of the scene?

There is many solutions possibles for your problem depending of the level of realism you want to achieve. If there is a lot of blinking LEDs, it will be probably simpler to fake the average illumination of the whole set. If there is only a few LEDs on at a time, it will be probably more cost/time effective to get real illumination from those few sources.

Hi,

Thank you for taking the time to respond.

Your suggestion sounds great.  Would you amplify your directions, i.e.,

1. How would I create the glow layer for the computer lights - and

2. Regarding the two renders -- do I understand to render the diffuse option, and again with the glow and then composite in After Effects?

Thank you,  again.

Hi,

To create a glow layer map - just use a version of your top diffuse full texture map. Then make black the colour of the elements that you don't want to glow. Make the elements to glow white or degrees of grey to white, depending on intensity. But I've just usually just used a black and white map, the subtlety of degrees of grey don't really make a difference unless your camera is really close to the object.

For the compositing, I'd render once for diffuse with all textures and objects active/ on. Then in the second render turn off/ hide all non-glowing objects, turn off all lights, turn off diffuse textures and just keep active the glow map on objects. Essentialy the render will be all black and only the glowing areas will appear. Then just composite both renders in AE or similar program.

Hope the above helps.

Glad to help. Just one thing I forgot to mention.

If your camera is moving and glowing objects are obscured by other objects in the move, don't turn hide/ turn off the non-glowing objects. Just disable all textures on them so they render black but still obscure what needs to be obscured.

I made this mistake in the past and had glowing bits where they shouldn't be. Yes, it was all spaceships ;-)
