is it possible to have a 3d backdrop like an office, and be able to create a bluescreen set (chairs and desks painted blue and positioned at the same 3d model distance from the camers) and compost it all?

No, only organic material can be turned into compost.

I think i understand what you're trying to say,

Do you mean that you are going to create a live action set where everything is blue, then create a CG 3d set that matches where the chairs and desks are? If so, that would work. As long as the people arent blue too smile

For best results on DV tape, use green color though, it picks it up much better.

PS Pooky, how do you explain DXM if only live action things can be composited either on or in things? Pretty sure they used a 3d city. wink

Yeah but if the chairs/desks are even a milimetre wrong it will mess up everything. You'd be better off using a REAL office, no?

Of course, live action is always the best way to go, but if your expirementing with something, or just want the challenge, then by all means, try what you must smile

Aligning stuff shouldn't be a problem in your 3D app though, you just set the background of the viewport to be your scene and position all the objects from there. For freehand camera just add some markers to the blue and use a camera tracking software.

Would I be right in thinking that you want like a "Star Wars Office"? which would be difficult to put together yourself.

This sounds like a massive amount of work to be honest, a simpler method would be to use a series of layers using either CHromy or Alam or even both.

Start with the picture of the offce room as a backdrop
Then garbage matte out the chair film the blue screenacor sitting and then using chrominator merge the two with the back, then do the same for adidtional furniture.

I'm with pooky on this one tho, I'd try a real office, or speak nicely to someone who has one, it's always worht asking.

To do it any other way sounds like a nightmare

Hope this helps
