View Full Version : Help: blood cells travelling down a vein
10 October 2003, 01:10 AM
I need help with an animation I'm doing, with blood cells travelling down a vein.
Particle systems don't sem to work as there is no collison dynamics btween the particles and with the large amount of geometry rigid/soft body dynamics keeps chrashing.
Any ideas on alternatives would be appreciated.

I think you can accomplish that with Effect>Create Curve Flow and Particle instancing.
It worked for me once and you can still make your particles collide with other objects while finding their way through the "veins".

But will the particles perform dynamically when they colide. I found the particles passed through each other. And when they collided with the veins they just bounced off, no spinning or collision dynamics.
As this animation is being shown in the cinema it needs to look very cool or the mistakes will show up big time.
Also I found with instanced particles I can't seem to give each particle random spinning movement. they all just spun the same way as the original which defeats the object.
Does anyone one know of any mel scripts floating around that can do this, they used one on the body story to do this and I could sure do with it.

try putting a radial field on the particle with small value so that they repel each other. Check this site for the idea.
