Space & Sci-fi


Gerry Anderson's UFO

Marc Martin has the best site dedicated to this series, which provided me with the idealised plans used to create the model.

It's very clear that different proportions were used depending on the scale of the model needed for a particular shot, especially how far the bottom perspex shell curved upwards around the strobe, and the position of the 'aerials' (connection points for the suspension wires and power?). They were roughly in the middle for smaller models but much lower and nearer the rim on larger ones, presumably for great stability as the middle silver section and lower strobe spun independently of the outer shell, as for example in Computer Affaire (into a forest), Flight Path (on the moon), and The Psychobombs (slow descent into trees).

I deliberately created more detail simply because when seen in close-up the model would otherwise be rather boring, so what was simple ribbing has been changed from my first rather flat rippled attempt to sharply defined vanes that are highly reflective and so hopefully create a nice glittering effect. I also made a small change to the motion, obviously keeping the central spinning vanes and lower strobe but keeping the bottom dome and especially the thrusters static along with the top dome and everything above the green ring, for having spinning engines makes absolutely no sense for any kind of stable flight and descent control, though even here there were vast inconsistencies with some models having only two exhausts (Destruction) and the larger models not having anything protruding below the lower dome so that they skidded easily.

 

Stills

Two images above my bland desert. As the vanes and domes are slightly reflective, some areas have a yellow tint due to the sand beneath. The domes are deliberately rendered without refraction otherwise the ribbed vanes are too distorted to be clearly visible, and the original model perspex didn't have any noticeable refractive qualities anyway.

All new renderings & animations with better effects and corrected textures arriving Q3 2021.

Cliché

Flying in space from the sun with deliberately clichéd lens flare.

Flyby

An animated fly-by composited with a 'real' background (Split Rock Lighthouse, Two Harbors, MN, USA). There are shadows, reflections, and clipping as the UFO flies behind the lighthouse; the foreground is also clipped in relation to the ice so it doesn't have reflections, just shadows. It's an incredible cheat, but adequate, and the sense of depth is good as I didn't have to resort to scaling the model which would have looked wrong anyway. The most obvious mistake is that the shadows and reflections are on a flat surface, so nothing takes into account the roughness of the actual terrain, and of course the CG image is far too clean. The UFO's rotation is also slower than it ought to be, but it was tricky finding a balance between seeing detail and having an incorrect sense of reverse rotation due to a strobing effect.

 

Animation Sequence - 3 Events

Part 1 : Crash

A missile fired off-screen from Sky 1 homes in on its target, which then crashes at the edge of a forest (pine trees, of course).

A learning study in volumetrics (though I was originally more interested in the motion): missile trail, missile-impact explosion smoke and separate sparks, dissipating orange and red smoke from the UFO and red smoke from the vane that was blow off, three sets of ground impact debris with one moving as the UFO skids, plus some dust. This is the first time I've attempted an animation of this complexity (all I've done in the past are relatively simple fly-throughs), and was a wonderful example of the large gap between knowing the theory of how something is done and actually setting up the multiple FX emitters and arranging them in different combinations affected by wind and gravity, whilst all the time being 'aware' of objects and so not passing through them.

Part 2 : Firing Laser

Having crashed, the UFO fires its laser at a ground mobile.

Part 3 : Exploding

Then it blows up in stages.
