Hi
Im trying to add boat wash particles to a boat project I am working on And I have searched everywhere in sl for examples of this so I can get an idea on how to script it but have been unlucky so far so I hope somone can point me in right direction here .I have been to ivory towers and I do already know how to make particles I am just looking for an example as a template.

thank you
Eazel

hmm, might be easier to use one large particle picture that repeats rapidly while the boat is moving. the PSYS_PART_FOLLOW_VELOCITY_MASK should make make the particle trail correctly as the boat moves/turns. i think that's the same method that footprint particles use. my quick search in the forum didn't find any results though. maybe the particle lab?

Thank you that would be a help if you can find any .

And thank you Ruthven I will try that Ive also been experimenting with drop age and size and that works quite well because you get a nice spread as the wake gets longer. I think to really get it right im going to have to draw something in ps so when the wake spreads the particle it seperates into 2 wakes.

Any other ideas would be welcome .

JP Sample Ripple Script from The Particle Lab http://slurl.com/secondlife/Teal/180/74/21 may provide a starting point; most boats I've seen seem to use something based upon it;

// A sample script from the Particle Laboratory of Teal
// You may copy, mod, sell, spindle, mutilate this script as you please.
