Glow from a cinema screen
Hello, I’m hoping somebody here can help me. What I’m doing is this:
I’ve built a cavernous 3D room with a giant video screen at the back of it. The camera is way at the back looking up at an awesome angle and spotlights scan the darkened walls.
Is it possible to have the image on the cinema screen glowing and thus putting out its own light to reflect off the side walls?
As a bonus I’d also like to possibly add a projector so you can see the beam of light shining from the back with all dust etc across it. That’d just be a bonus feature though.
Any help would be greatly appreciated, thanks.

There’s probably a million ways to acheive the effect you want. For the beam of light you’ll need something like Trapcode Lux, won’t give you particles of dust but will give you volumetric light. There’s a bunch of other ways to acheive the effect but I feel Lux is the easiest.
To put out light to show on the sides I would set up a light on facing from the screen, for an easy (but not as accurate) effect just set a wiggle expression on the intensity. For more accurate you could set try putting the light behind the video screen and using the screen as a gobo so the light actually comes out accurately.
Hope that helps.

Fantastic, thanks a lot for your help.

Sorry to come back to this, but how would I use a video layer as a gobo?

This projector for the look of the image embedded in the beam, and true AE 3D at that (yes, you fly that camera around the room), comes with a project file and is hands down the best solution for a projector beam, and one of the top 10 AE projects here (IMHO). Thanks Filip Vandueren :

Here is a post from last week to get dust in a beam of light using a Script for a light, in case you don’t have Lux:

But I dunno know how you’d incorporate the two offhand.
