My son has a couple of frisbees shaped like the Identity discs from the movie Tron Legacy. I was looking at them and thought it would be fun to have a go at making some Identity Discs in LightWave.

They're not perfect, and I guess probably very inaccurate compared to the movie props but hey, it's just for funsies.

Here's a YouTube video of the discs showing the animation of the lights, best watched in HD to see the flickering of the 'blades'

how did you get the blades to flicker/rotate?

Pretty easily actually, First off the geometry doesn't move, the rotation is purely a texture effect (Although the geometry is deformed by a morph to extend and retract the blade but this does not effect the flicker).

I UV mapped the blade mesh so that a texture map would wrap all the way around the disc. I made an image to control the transparency of the surface and placed it using an image node. I then used a scaler node to control the U offset of the image node and enveloped the scaler value to offset the image by 1 every 30 frames.

The effect of this is that the image gets pushed all the way around the disc once every second.

Alternatively, each light could be assigned its own surface. eg, Led01, Led02, etc and you just simply envelope the luminosity/glow channels, Individually. Allowing you multiple things, such as all lights stay on and a light which is off spins around it.

All it needs is a bit of number crunching on paper to get your timings right depending on your FPS.

Looks cool! I like it. It's a bit too glowy for me though.

I know it's a fan thing though, so it's all good. But sometimes less is more..u know. Great work. :)
