View Full Version : Particle Problems - HELP PLEASE (75b)

03-24-2003, 09:11 PM

First time poster, long time lurker.

I am having some problems with the attached scene.
Can anyone tell me what i may be doing incorrectly ?

The scene consists of just one emitter parented to a null.

The Null moves upwards over 300 frames.
The emitter and particles should follow them.

Instead the particles move up before the Null does.
So at frame 0, the particles are already a few metres in the air.

This is obvious at the frame 0, when you can see the particles
floating above the actual emitter. A real problem for making smoke for an exhaust, as it leaks badly.

Why is this happening ? Please anybody?

I have heard other people complain of 7.5b and particles.
Could this be a bug in 7.5b?

Thankyou for any assistance. I am very confused.

you have to bring the patent motion (in the Etc tab) down to 0 or close to.
Because with parent motion on 100% the particles are going up like the parent before they are doing anything else.

As a reference you can look at the moskitodown scene from the Sigraph content.

Good Luck, Robert

Thankyou very much Robi.

Yes that did fix the problem. Thankyou.
I have made similar effects many times before.

I was just losing my mind.
I will sleep now.

Thankyou once more.
