This is also a 3D tracking practice but with this one, we are collaborating with the Maya class to implement and integrate a 3D model that we came up with to after work on the compositing part of the process.
So first is what we have done already to the clip, track it, and create a clean plate of the video. All of this process you can find it in the post about CLEAN PLATES.
While we are creating the patch, we can start modeling what we want to implement in the scene. First, we looked at some references, I chose these images of a steampunk-style machine/motor.
This is where I start modeling it. Here you can see different stages of the process. From the first model to texture and lighting.
After we had the model created we can export the camera and track from nuke to import it in Maya so we can render the model with the right camera and make it move along side the clip.
We also create some shadow catchers to try and match the light from the video we have. As well as some planes with a aishadowmatte material to cast shadows on the walls and floor.
As you can see I have duplicated some of the geometry to fill up more the room.
With all this set up we can proceed to render the model and after import back in to nuke and do the compositing part of the project.
Once in nuke I start to work on the roto for the clip, otherwise, the model would not look like is in the room at the end.
And then we combine both the clip with the model I created for the final result.
This is how it looks at the end.
