VFX Breakdown: Forest Fire

Posted on: No Comments

The 3D tracker in Nuke did an okay job on this shot, though it took a little more time to get a good track. Although the resulting point cloud sticks well, it’s distribution never matched a real world camera move.

I sampled four different forest fire elements from National Archive footage and projected stabilized versions of them on to cards to use with the tracked camera.

The larger smoke plumes are actually still frames with 3D luminosity based animated distortion to give it a faked sense of movement.

Lastly, the reflection in the lakes was a second flopped render of the same element masked into place.

VFX Breakdown: WW1 Battle Field

We had two live action elements for this shot, a dirt explosion and some dark billowing smoke. Some burnt trees were also photographed.

The rest was cobbled together from stills projected through a camera onto a ground plane and cards.

The ground plane has some procedural displacement to match the hills and valleys in the comp.

The camera shake is animated using TCL random expressions whose amplitude is an animated Nuke nob.

VFX Breakdown: Avalanche

Posted on: No Comments

One of the major shots for the season, we had one artist on the avalanche R&D for a month. Another artist worked on some smaller particle and fluid interactions.

Another artist was on the plane animation and mountain ground plane modelling.

I comped all these passes together for the most part using luminosity values of the avalanche to mask the plane.

I also had to re-project the matte painting of the plane’s skid marks through the 3D animated camera to integrate it with the background plate.

VFX Breakdown: Ice Shacks

Posted on: No Comments

This shot required the addition of a few ice shacks into the plate.

From stills taken by the supervisor, I made 4 unique shacks – one for the foreground and 3 for the background. The shacks are graded to match the plate, adding in light leaks and highlights.

To tie everything in, I added some haze using fBm noise. I created the falling snow using particles applying the alpha channel to a gradient so that the flakes are light over the dark sky and dark over the light snow.

Add camera shake and done.
