Hi

I am having trouble understanding how to make hair from some curves...i'm a noob so please bare with me. When I select a series of curves grouped or otherwise an 'make curves dynamic' I only get one of the selected curves in the hair system. Why is that?

Additionally let's say I want to tack on some new hair using curves into an existing hair system, how do I go about doing that?

Thanks!

Hi,
Make shore you select all curves, not the group, and apply "make selected curves dynamic". They all will be driven by one hair system. You can also use "Assign Hair system" to transfer hairs from one system to another. If you wanna tack hair to some object you can use option box of "make selected curves dynamic" and choose there "Attach surface to selected object" and "Exact shape match" , or "Snap curve base to selected" - if you wanna physically move hairs to your geometry. It's also usefull to rebuild all your curves and freeze transform them before applying hairSystem. Hope its all.

thanks for responding. I got the basic curves transformed into hairs just fine but I don't quite understand your suggestion i quoted above. Can you explain?

also, I am finding that the hairs move around to violently - I shoul say that I am using the hairs not to represent real hair but to simulate strings or cables that bunch together. I have that going but they are wiggling a bit too rapidly. I have tried playing with the myriad settings but I can't seem to find the exact one to control that behaviour...

If the cables are wiggling too fast it could be that gravity and/or stiffness are too high. Generally for things like ropes you can make stiffness zero( so it can flex ). With stiffness high the cable would become like a thick wire and wiggle like a taught spring. (note that if you increase iterations to avoid stretch you need to lower the stiffness to compensate)

The speed at which a rope will swing is determined by the length of the rope and gravity. You could have gravity set to high for the scale you've modelled at. Air friction(drag) can enter into it but not so much with heavy cables.

If they seem to springy you might also wish to increase damp.
