I'm fairly new to Maya, about 4 months now, and we got a job in calling for some 3D animation. The client wants the scene to go as follows.

Start off with a shot of blueprints.
The buildings then animate on to look like they are being built on.

I got the modeling done easily, and the texturing was no problem. I did a test render and added a building effect in After Effects that looked fairly good using various masking techniques, however this was done on a still image. The masking becomes much more complex when the still is replaced with a movie containing camera movements.

I was wondering if there was any way to do this effect in Maya, I'm sure there is and I just don't know about it.

Thanks
