What if I wanted a flicker?

I have this star drawn in PSP then copied and rotated it. I want to make an animated flicker or twinkle effect with the two textures with a texture emitter.
My question is:
Am I on the right path, how do I animate these to get the twinkle effect from my texture emitter?

That's a good path. Adding a particle script will help a lot. Visit the Particle Laboratory in world to see how to do it if you don't know already. I can't get in to grab a LM for you right now, but you can find the place very easily by doing a Search. As for your two textures, you can alternate between them with a simple script.

Particles are one way to go. Another is to animate the texture.

SL utilizes "filmstrip" style animation. All frames of the animation go onto a single canvas, which you apply to your object. Then you use a script to tell the object which part of the canvas to display when. For a simple twinkle effect, you only need to cycle through two or three frames, a really easy setup.

You'll find an example texture animation script in your library. See http://wiki.secondlife.com/wiki/LlSetTextureAnim for an explanation of all the variables.

ohh!! thanks so much!! Now i have my texture working like I want.. on to the script to recongnize the object to poof out when its near.

Thank you thank you and thank you!
