Hasta La Motion!

Before I get into details, to summarize in 1 sentence: I created a 3D environment in Nuke, boujou tracked and completed the first shot, I now need to import a boujou camera for the 2nd shot needed the same environment but that camera I input requires a new ground plane, throwing my environment off. This is the first time I do a 3D projection in Nuke and need some help, please!

Details:

I have over 5 different shots which are in the same environment, so I tracked 1 shot in boujou, imported to nuke, and built my environment using 3D projections all in Nuke with 3D geometry, etc, it took 2 days just to build. The first shot is rendered and approved by the client and looks great!

I thought it would be a matter of replacing the back plate, importing the new camera, etc. I even gave my separate layers from my matte painting extra room so when the camera pans, etc, thinking it would all work.

However . . .

I then tracked the 2nd shot in boujou, imported the new plate and camera into Nuke, and something is wrong!!! I did not see this coming!

The new camera has a different z position, and the ground plane is at a different height. If I offset my ground plane I already set, I ruin my environment because everything will be thrown off, all the 3D rocks and other things I build laying on the ground plane, I cant do this, there must be a work around.

Is there a way that I dont have to realign the ground plane and everything? I have over 5 shots, and this is due very pronto! :rip:

I think if I can shift the boujou camera so its at the same position as the first frame as the camera when I first built the scene it should work? How can I offset the cameras position without affecting its keyframes if thats the fix. If that does fix it, what about the ground plane? I see that shot 2’s ground plane should be significantly higher than the shot 1 I built the scene on.

Please help!!!!!! Im really stuck at this point. Thanks.

Attached is a picture of the 2 different boujou cameras, the one in green represents this new one which is way too close as you see which requires a different ground plane position where the actors sit on, and the other one is from the last shot which is 100% good.

What is going on, and what do I do!!! Is it as bad as I think? If so I better go to work. Thanks.

Oh and by the way, this is the first time I’ve done 3D projections in Nuke, so sorry if I dont understand fully if it is a simple fix or Im overthinking something.

:confused:
