Modelling a steam engine in Maya and comping in Nuke (collab. unit)

Inspiring by this reference from Sketchfab I start to model a steam engine in order to import it into a 3d tracked scene. The engine must be rigged and that’s the main task for this project, the steam engine has to be animated.

CAMERA SCENE imported from Nuke

That’s the 3d view of the space in maya, the green points are locators from the 3d tracking in Nuke.
I’ve recreated the space using planes, lights and imported the camera from Nuke.
This is still a ‘”work in progess””, I have to finisih to render the machine, to adjust lights, multipass comping and roto out the walls in nuke.
I downloaded some textures from texture heaven and I use arnold AIstandardsurface through the hypershade to render the model. I’ve created a new source of light to get the machine’s shadow visible on the ground.

I then export the multipass file to nuke to comping into the scene.

Multipass Compositing

I 3D tracked the video first and then I used this bulb model from our teacher Aldo to rebuilt the beauty into the scene with multipass

As second exercise I’ve picked the 3d projection video from week 3 about 3d environment and I implemented a rendered sphere created in maya

3D Tracking

Tracking a 2d video to create a 3D environment. I have applied to the plate axises and cards in order to make visible the 3d space.

I have issues when I create the camera, it always appears under the ground level…

Houdini

Week 1

During week 1 of houdini we practiced with modeling tools creating a house model

Week 2

In week 2 we have created particles to apply on our testgeometry.

Final result

Week 3

During week 3 we practiced on how to use the material fracture node as well as the new RBD Bullet Solver node. Here I am going to build a rough building and destroy it using those previously mentioned nodes.

Final reel

In this plate I tried to use most of the tools I have learnt during the first term using Nuke.

I first stabilized the footage and then I denoised it in order to track it way better. After that I started to rotoscope the main character because I want her always to be in front of everything I have added to scene.

I did some color grading, white balance and color-matching with all the images and videos that I added to the scene.

The original plate had some details which I didn’t like, for example some stains on the walls, tubes, people and signs. So I did some clean ups and replace where I could.

Clean UP (rotopaint)

First exercise: clean up
the process on Nuke
From this plate I want to remove the slippers from the ground in the foreground
The problem here was that the clean up shape was continuing going in the scene
This plate was complicated due to its movements and changes of prospective

I have removed the cars on the right and some elements in the field

CornerPin & Planar Track

FIRST EXERCISE

I tracked the three spaces with Planar Track and CornerPin allowing me to match the three posters.

VIDEO 2

Original Plate
Using PlanarTrack I tracked two areas of the scene, applying then the two elements (graffiti and the big yellow sign)

VIDEO 3

Original plate to stabilize and track (cornerpin and planar track)
Here I added several elements:
Starting from the left I added a bansky graffiti using planar track, the element is located below the pole (as it has been rotoscoped). Then I applied the mandalorian poster with cornerpin which is below Antoni (rotoscoped), letting the black lives matter sign emerge from the original video and the anarchy logo of bansky. Finally on the floor is the number 2020 applied with a corner pin, placed underneath the walking Antoni
