Britain’s Most Extreme Weather and How The Universe Works

This past few months I’ve been beavering away at Lola Post on 2 series of shows, creating VFX of a weathery, Earth-scale nature for Britains’ Most Extreme Weather, and shots of all scales for series 3 of How The Universe Works.

Ordinarily I’d put together blog posts before a show goes to air, but in the case of Britain’s Most Extreme Weather it slipped from my mind as soon as I rocked back onto How The Universe Works. Much of my weathery input was particle systems and strands, either using existing setups from previous shows or creating new ones as appropriate. A particular favourite of mine was a system showing the movement of air around cyclones and anticyclones; A strand system that rotates particles around many points, allowing them to move fluidly from one direction to another as if air, all wrapped around a lovely spherical Earth.

How The Universe Works is a series I’ve been on for many many months now. I first started on it in November I think. The first episode, all about our Sun, is to be shown on 10th July on Science in the USA.
For that show I took Lola’s existing Sun cutaway setup, introducing a more boiling lava-like feel through judicious use of animated fractals and grads.
Overall I’ve worked on 8 episodes with a handful of shots in each show. After all that dedication to spheres in space I am now supervising the VFX on one of the last shows for this series!

More geeky details and videos for both shows to come!

South Bank Show Trailer

A few months back I worked on a trailer for the South Bank Show, featuring Melvyn Bragg walking through the Leake St tunnel under Waterloo station. Bragg was shot on a greenscreen, with the environment being recreated in Softimage by myself and fellow freelancer Rasik Gorecha.

The obvious question there is why? Why can’t Mr. Bragg just go into the tunnel and we shoot it there, huh? Well, there are a few obvious answers to that. The tunnel, itself a road with access to a car wash half way down, is dank, contains certain undesirable types Mr. Bragg would probably best steer clear of, and is continually in flux thanks to it being one of the few areas in London where it is legal to graffiti. It’s also not the most comfortable of places to sit around in for long hours on a shoot. The other reason is that lots of the graffiti was to be replaced with animated posters and artwork featuring well known faces from the arts. That process is a lot easier if created digitally and lit using indirect lighting solutions.

My input on this was twofold. Firstly I set up the lighting in Arnold. After an hour or so of experimenting, the solution found was to place shadow casting point lights in the ceiling under about half of the strip light fittings, plus a spot light at either end of the tunnel. Additional fill lights were used to brighten up the nearest walls. The lights in the walls toward the back of the tunnel are merely textured models and not actual lights.

One of the things with a Global Illumination solution like Arnold is that it can lead to fizzing. One solution to lighting this tunnel would be area lights. This was ditched as a plan extraordinarily fast as it led to lots of noise, plus the modelled lights themselves act as bounce cards essentially negating the need for area lights at all.

Rasik had the majority of the modelling done by the time I joined in the project but was yet to embark on cables. Whilst he set up initial texturing, I became cable monkey. I modelled cables and brackets, trays for them to run along, pipes and all sorts. It took a few days of continually modelling cables before I’d finished them. Simple stuff but it really added to the believability.

The top of the two images above is the model with finished textures and below that is the finished lighting.

The final trailer is not as it appeared on Sky for 2 reasons. They added their own logo at the end, naturally enough, and they own full copyright of the sound bizarrely, so mine’s a silent movie. Add your own ragtime soundtrack as appropriate.

Brand New Showreel!

The work in the following reel is created using Softimage, Terragen, Nuke and PFTrack.

Ashdown Forest gets a new look

Whenever there’s a break in work and I’m aching to do my own thing I work on a few ideas. One of these that’s taken a step in the direction of starting is to take a piece of footage I shot last year and alter loads of it. It’s a 9 second or so sweep across the Ashdown Forest, not too far from here. What I’m going for is a near-future post-war landscape with much destruction. One of the things to suffer will be a tractor, shown below. I’m a bit off finishing the model let alone the texturing, but it’s nice to let you lovely people see what I am actually doing when not working!

[Edit] Modelling Done now! Will dink it a little then texture:

Kenneth Branagh picks up Television BAFTA for Wallander

Last night was the Television BAFTAs, this being the time of year when shares in sequins go through the roof. The Best Drama Series Award went to Wallander, produced by and starring Kenneth Branagh.

So how does this relate to me in the slightest? I did a couple of VFX sequences in that I’ll have you know! All being well, one of them will be in the show reel I am currently piecing together. There was a lot of fog at one point, some of which is 3D fog created in XSI’s ICE engine then composited in After Effects, the aim being to cover up gaps in the smoke machine’s efforts.

BBC iScience was on iPlayer

[Edit again!] iScience clips are now online at BBC – Learning Zone.

[Edit] Now that March 12th has past, iscience is now longer on BBC iplayer.

My work on BBC iScience is on iplayer again now. This particular episode is nanotechnology. (Can I get a woooOOOooo?) Pretty much all of the 3d graphics are my creation, even the ones which seem at first glance to be 2d. They are cel shaded 3d! (Same approach as on Futurama)  They include animations on fusion, uv radiation, cell division and all sorts.
