Animating Particles - particle path showing in render prematurely

Hey all.

I’m definitely learning a lot from this forum. Thanks to all.

Anyone have soem notion as to what’s happening and how to correct the following …?

Testing an anomation, in which I have my mannequin smoking a cigar. The particles do not start emitting until frame 1100 or so. Between frames 1200 - 1500, the mannequin moves the cigar. I have the particle parented to the cigar, so it follows, as expected.

When I go back to frame 1, the particles are all in their original location, but when I render (either single frame or a sequence), the render contains the particle path. Any ideas how to clear it out from the final renders? :confused:

TIA

Is the Path Parented to the Particle Emitter? If you don’t sort it out could you please post the blend.

Actually, I wasn’t using a path; at least, not yet. I had parented the emitter to an object, inserte locrot keyframe, moved the parent, inserted another locrot keyframe. I know it’s a cheat. :rolleyes: that’s part of learning, and it seems to work for this animation.

The blend file is currently 15M; I’ll strip out all but the particle and cigarette, and post that, if that would suffice.

Thanks.

Bizarre…

Okay, I grouped all except the cigarette, the 2 emitters, and the table, and deleted them. to make sure the problem was still present, I did a quick render of a random frame, and teh particle trail still showed prematurely. Because I had forgotten to save my project first (oops! :o), I undid teh deletion, and did a test render. Now teh particle trail is gone. I tested in a few different keyframes, as well as a quick 150-frame animation. The deletion / undo seems to have cleared it…

Thanks again all, and sorry to bother you on it.

I stand corrected. again The pre-mature particle path is back. The .blend file is located at this URL:

Thanks to all that take the opportunity to look. And please excuse the crudeness (i.e. lack-of-finesse) of some of the data structures in there… :wink: still learning the app. Plan to clean it up a lot as I get more proficient…

HI all. Was wondering if anyone was able to pull down the blend to see what might be up with why the particles are leaving a trail prior to their movement.

If the file size was a factor, i’ve zipped it up to around 2MB, and the url is now http://www.magma.ca/~jgolden/BlenderArtists-to-check.blend.zip

Thanks again all.

On the SmokeLow, in the Particles tab, unclick “Unborn”.

Thanks muchly. that wotrked.

blush I figured it would be something simple. Just didn’t figure it would be that simple…
