boujou and scaling issues in AE
he folks,
this is a problem I’m running into when I import boujou data into AE. Everything lines up okay and tracks fine. That’s not the issue. It’s just when I make a layer 3D, like some keyed footage, AE instantly tosses it way out into 3d space and I have to zoom way out of the comp to even find it.
Then I have to spend a few minutes lining it back up and placing it in the shot and usually reducing the scale of the layer down to about 1-5%. This also makes moving objects within the comp very difficult being that the layers move in huge jumps instead of small precise, incremental moves.Any idea as to how to correct this?
Thanks.

I don’t know what boujou puts in your composition, because I didn’t use it, but I believe it places a camera and some reference layer, or layers right?
I would at first analise what I have, i.e. what is the position of my camera, what is the point of interest, do I have any null object as a parent, what is the position of the reference layers and so on.
Then if you turn any of your layers into 3D, you’ll have to check out if the position of it is anything close to the references created by boujou (assuming it creates any). You will certainly have to do some work to manualy position your layer. I can’t figure out in what situation you would have to scale your layer down to 5% to match the scene. Logically you would rather have to scale it up a lot, but who knows?
Let’s say that you have to scale something down to 5% to match, but want to have a better control over scaling. Why don’ you place some null onto the same position as your layer, parent the layer to this null, scale down the null a lot, and then tweak the scale of your layer. In this case you play with values close to 100%, which is easier.

I think if you multiply the zoom on the imported camera in after effects by 1.111, everything will line up correctly. I think I remember reading that somewhere regarding boujou and afx.
Best of luck

The boujou -> AE workflow isn’t quite as smooth as it could be…
I haven’t had a chance to try out these methods yet, but they sound good. Seems to be a good little conversation going in each thread.

I had the exact same problem, seriously. I then found this very helpful website:

Where it says to export in the “.ban” format, ignore that and just use the “.ma” format because that’s what the updated Boujou exports to (older versions only supported the 2d3 plugin for AE.
