Hasta La Motion!

Hey guys I’m a noob when it comes to this so I’ll be clear as possible.

Currently I am working on a short film. One of the shots show a person pouring milk out of a carton. The film is shot in live action however I want to insert 3d animation for the carton and the milk.

Im using

Maya 2011 for the modelling & rendering,
PFtrack for the tracking composition and
Realflow 5 for the milk effect.

I insert the 3d carton into PFtrack and use its tracking to link the 3d object to the live action footage. Exporting this into Maya shows that the camera moves and not the 3d carton.

Therefore…

How am I supposed to get the carton to pour milk if the 3d carton doesnt move? Realflow requires the 3d object to move as to get the physics, right?

I hope this is clear enough, im tearing my hair out here any help would be fab

cheers

Hi all,

I’m having a bit of a problem that I haven’t been able to solve.

– I have a 3d tracked camera and a plate.
– I have stabilized the plate by converting two 3d points to 2d and used that data in a tracker node (stabilize).

I then get a smooth plate that is stabilized on x and y. But now, as I want to continue to work, my camera doesn’t line up any more as it’s movement is based on the original plate. I was thinking, as all I’m doing to the plate is x and y stabilization, I should be able to use that data on the camera as well and stabilize it. Somehow.

The reason I need to stabilize it at all is that I need to get a smooth camera exported from Nuke and use it to shoot elements on a motion control rig.

After I’ve composited my elements I want to bring back my original movement, and that should be as easy as just reapplying the motion with the inverse of the original track.

Earlier I’ve been stabilizing the plate and then done a new 3d track of that plate, but it feels like there should be an easier faster way, as all I’m doing is a simple stabilization.

Anyone have any idea?

Hi, I’m facing a network workflow problem with Nuke.

I’m working with a team of compositors and they need to pass the same script each other so the read nodes must be pointing at the same network place. Using local files isn’t an option cause we need to pass the scripts each other very frequently.

The problem is the speed: working in an 1GB ethernet network is like 10 times slower than do it localy. I think working this way isn’t reasonable due to low eficiency but at the same time, it’s better than having to relink all the files constantly. I’ve tried to use DiskCache after every read node but they only cache files for the script used, so if I save a new version the cache is missed and I must preche everithing again…

I’m very frustrated cause Nuke is suposedly designed with network and team work in mind and cannot see how is this possible with the actual workflow since working in a 1gb slow network (not fiber channel) isn’t practical.

Any suggestion?

Also I would like to know how are you people working with teams in network environments with Nuke.

Many thanks.

Hey all, I just wanted to let everyone know that I have a new tutorial up on my site. It is a procedural object for creating a string of Christmas lights. The approach would be applicable to many other problems that you might run into along the way. It could be used for ropes, cables or anything else that you need strung up between two points and have sag between them. Take a look and let me know what you think. Thanks.
