Hi,
I'm working on a model that I would like to animate some part of.
[attachment=24943:coils.jpg]
Here the red rings of each coil should glow, while the timing of the glow should make it look like it is going down the complete coil.
For "normal" animation by skinning or even vertex keyframes I have the habit of keeping all of the vertices in one object. But as far as I can tell there is no good way to keep all the rings in one object and still animate this color transition separate for each ring. Maybe I could have 2 sets of uv's? But even then I don't see a flexible way of changing the timings: duration of glow, delay between next ring to start glowing, delay before first ring starts next sequence.
One solution I see is making each ring its own object so it can have its own timing variable for the shader. But I don't like this as it increases the draw calls by a lot.
Is there a better way to animate something like this?
Thanks,
Mox
