Tornado of magical dust

Every time I make a change to a prim I see the side-effect of a tornado of magical dust around the changed prim for a few seconds. This may be a cool effect when I change a frog-avatar into a prince-avatar, but in many cases this effect is undesired. I have seen prims built by other people that changed without this Tinkelbel-effect. How is that done?

All that is is an effect that shows you which prim you've selected, and let's other people know as well. It's a permanent thing for the prim or anything like that. I believe if you go into preferences there is an option to have it turned off, as well as an option to change it's color though!

I am not selecting the prim. It is merely sitting there and running a script. When the script decides it is time to change colour, it does change color, but I also get that tornado. If I want to build e.g. a chameleon, I want it to change color without causing a tornado.

Hmm, I've never heard of this before. Is it part of the script to cause the tornade effect? If so, you could drop me an IM in-world, and when I get home in a couple of hours I can give you a color change script I have that causes nothing like that.

The effect you are seeing is built into SL and cannot be removed.
You, as creator/owner of the prim in question will get to see the "tornado" as you describe it so you know which prim or object was affected by a change or which prim or object is talking.

However, this effect will not be visible to other players. They get to see it on their own prims though

Wow, interesting!
I will let my alt have a look at it when I get back home...

I'd be willing to lay odds that the object that's changing colors is "speaking" at the same time. the particle swirl is a visual cue in SL to let you know which object just spoke. I do not know of a way to turn it off, but it may be under the debug settings. only the people who can actually hear the object "speaking" will see the swirl.

Speaking?

Well now that you mention it: It does llSay() the RGB-values, just for debugging.

I was too busy yesterday to get my alt to look at the object, so there are now two things to test when I get home this evening.

As Senuka said its the spaking that causes it. Anyone that can see the text will see the sparkles. Which with an Say(0, ...) is everyone.

Is that true? I thought it was only the object's creator that could see the particles.

Yes it has been solved!

I first let my alt have a look, but she saw the tornado just like I did.

Then I commented out all the llSay()...

And the tornados are gone. So the speaking was the problem!

Thanks all for helping me with this!
