Hi! I'm trying to create a fire trail following a spinning object. The C3 manual says(page 90) I should be able to control how particles inherit base object's movement but I can't find it from the program. Now the particles are strangely preceeding base object. According to manual the is also an oversample emitter-radiobutton to force the particle to be created continuously. there are gaps in the particle creation in my scene and I want to get rid of it.

You've probably already done this, but make sure that your particle emitter is grouped with the object that is moving or you can also select a "track" behaviour as an alternative method. Good luck!

Very good tip Mark! Thanks, Stan

Thanks Mark! I finally got it to work. One problem was that the emit type was wrong. Another was that I had created duplicates from one particle primitive. I wanted better control over where particles emit from and duplicated the emitter and shrunk its emitting area. The particles wouldn't react expectedly until I made each of the emitters a master. If I had been able to control all of the emitters with one master object it would have saved time a little. On the other had now have particles where I want to and they leave an arrow like trail just like I wish them to. The pulsing particle creation disappeared by changing the maximum amount of particles, just as you proposed. There is something wierd about the seed of the random generator, seems like it returns always the same value, but I don't know if it matters. Atleast this time it didn't. I hope the included image gives you some idea of what I wanted to achieve. This image was created in Photoshop so it looks a bit different than what the final movie does. The flames were rendered to be used as one layer of a video and the puck as another. Then they were composited in a video editing program. This way I could get the flame shine a little more. -Hannu Kulju hkulju@dnainternet.net

A hockey puck as fireworks! Looks like a cool assignmen HK. Post a link to the final movie if you get a chance.

I'll see what I can do. The puck is a part of a player introduction-video which is to be used in local hockey games. Meanwhile you might want to check one of my previous puck-animations at: http://www.3dxtract.com/cfforum/viewmessages.cfm?Forum=14&Topic=317 My alias is hkulju_873, so you can find the movie clip easier. It also has been used in local hockey games as a starter for the game. -HK
