Snapshots

Some snapshots from the final render..

Shot 1

 Shot 2

Shot 3

It's Roto Time!!

For my first shot, there is quite a fair bit of clean up to be done. As the CG Bow that is replacing the PVC pipe is smaller. The easier way out was to scale up the CG Bow, but there is a limit that I can scale the CG Bow, else the Bow will be out of proportion.

Slow-mo Effect

For the second shot, the idea was to show the flight the arrow, in other words, a slow motion effect when the arrow is flying towards the target.

During the process of getting the effect, there are quite a few obstacles. After many attempts using the different nodes in NUKE (Retime & OFlow), there were a few issues. Mainly due to the control of the nodes.

Thus I tried using Time-Remapping in AE, it was able to achieve the desired effect with better control too.

Composition Test

Did a quick test with a downloaded 3D bow, it seems like the bow has to be pretty big to cover up all the PVC pipe to reduce the amount of roto work. It seems to be totally off as everything is out of scale. It seems like roto-ing/ clean-up its kinda in-avoidable.

Integrating the Bow

The plan that I have to integrate the bow into the shot was to make use of the trackers that I have pasted on the bow and to do a track on it so that I can bring it into Maya as a Locator, allowing me to parent and match the movement of the actual "fake" bow and CG Bow.

So first step, to do a quick track in NUKE.

Next, to convert the tracker data into a 3D software such as Maya. I went to look for NUKE Gizmos to do the job but many failed to allow me to convert to FBX or any other files. 

I tried to use a Camera Tracker in NUKE, but it fail to track my points in the shot too. So luckily, I came across this website, where I can convert tracker data from NUKE to Maya, or even into many other file format. I can say it really very useful, the link to the website is attached below. No download required, just upload your file and "BAM!" they will convert to a folder of different files for different software packages.
