Hi guys:
My hurdle is I need a night sky and I want twinkling stars in it. So I searched the marketplace for a night sky dome with twinkling stars and I could not find one. (If anyone knows of such a dome please let me know
)
What to do?
I took two cylinders and scalled them to 250x250x1. I called one of them 'sky' and the other 'stars'.
I put my original starry night pic on the sky cylinder and then made an opacity by turning the pic to black and white, bumping the contrast, and inverting the colors. This created holes at every star position on the first cylinder.
Then I put the same pic , in black and white, on the stars cylinder and added a blue white glow on it at 50% strength. So they ended up looking like this:
Then I put circular motion on the stars disc at a rate of 90 degrees for every 400 frames. That produced a pretty good effect.
If you want fewer twinkles, color some of the stars on the 'stars' cylinder black. BOOM less sparkle! For larger twinkles move the 'stars' cylinder back a bit from the 'sky' cylinder. (I may have put it a bit too close on the example)
The effect is more pronounced on 'full screen'.
I'm still experimenting but I think it's a pretty good first effort.

Final Video Effect just shows black disk without stars showing, here, Pete.
Had you already played-around with Starlight 03 Particle Effect?, See iC5 Screenshot.
