That's the one I've been looking for!!!
Thanks for posting the link again Ian.
A group of students I work with recently wrapped shooting on a music video and I've got the job of teaching them Vegas so they can edit it.
I planned to make use of your Bump Map filter tips in it but couldn't remember what to search for.
It's now bookmarked and I'm a happy editor :-)

Ian,

Did this involve multiple tracks of the same clip, using cookie cutter or a cookie cutter type interface, or are the effects applied to only one track?

I'd also be very interested in learning more about this.

Mike - great! Glad you found it!

Brian,

I applied the Bump Map filter to a single track/clip as required - no need for the cookie cutter. Key settings are Light Type: Spotlight and Bump Height: 0. Intensity and focus etc will change the characteristsics of the light as required. In most cases it was at the end of the filter chain.

It certainly isn't perfect, and doesn't replace good creative light at the shoot, but it can give some really great dramatic depth - with the added bonus of being able to wildly experiment with it during the edit.

As for virtual gels, I never found a way to do this, other than to add another track above with a solid colour or gradient set to a low opacity setting.

Now there's a Vegas plug-in development opportunity - a decent artificial lighting tool, with virtual gels and gobos, volumetric lighting, etc . . .

Digital Film Tool's 55mm suite may have come closest to this, and included custom gel's but they never showed interest in Vegas support.

55mm is now sold by Tiffen under the product name of Tiffen DFx Digital Filter Suite.
