hey everyone. I'm currently working on a scene where I want blood to run down a characters hands slowly and drip off at a particular point. It seems to be going okay so far. Just wondering if anyone knows any tips or advice about a good particle system that would make convincing blood behaviour as it's a lot denser than water and tends to stick a little bit.

hy renaissance01,
on allan mc kay´s first DVD "Advanced Visual Effects #1" he deals with water and dripping systems: http://www.turbosquid.com/FullPreview/Index.cfm/ID/236836

on his website catastrophic FX is a free tutorial too:

Thankyou Yoni-Cohen and PsychoSilence for the help.

PsychoSilence. The Allan Mckay tutorial helped alot. Just wondering though. I have a drop of blood trailing down the hand etc. But they are individual drops following each other instead of a solid stream thats connected like blood. Do you know how i could counter this ? What sort of geometry should i use as my shape instance, at the moment im using just low poly spheres but im not too sure if spheres will do the trick when i render. I'm guessing this is why Glu3D and Realflow were produced :p hope you can help.
cheers

Actually. more particles and motion blur tended to do the trick okay. although if you know of any other tricks to improve quality. Id love to hear them. :)

Take a look into blobmesh for getting the particles to blend together... or pwrapper which is now sold separately from glu i believe. Pwrapper is way faster than bloblmesh. :)

From my experience, pwrapper works quiet better than blobmesh. and it gives more control to generate fluid mesh.
