I need to parent an emitter to the end of a hair system (Wire Breaking with sparks shooting from the ends) and every time I either parent the emitter or constrain it using the animation constraints the emitter will not move with the geometry. does anyone have an idea why?

The animation constraints do not know about the deformation of the hair - they only see transformation (except geoconstraints). Using geo constraint though isnīt working properly: you can select the last CV and shift select the emitter and do a geo constraint, but youīll notice that the emitter slights a bit along the curve.
The hair constraints donīt seem to offer a solution here. Hm .. interesting question.

Ok what you do is create a curve and turn that into hair(select the curve and go to hair>create new hair system). Then select the output curve on the hair system, select a control vertex on the curve and go to particles>emit for object option box and select curve.

That's it the emitter is now on the hair curve. This is also how you can parent object to hair curves just turn of the emitter rate to zero and parent you object to the emitter.

thanks guys... both of those suggestions worked. Unfortunately the solution I found was to just make an IK Spline joint system down the "wire" and made the hair system drive the joint chain. We then parented the emitter to the ending joint. If this ends up not being the best solution I will keep these suggestions in mind.. Thanks alot guys. I appreciate the quick response.

Im not 100% sure on this workflow and im not near maya right now but a follicle attached to hair curves? Ive found that follicles are my new best friend when it comes to the ole" rivet workflow. They deform along the normal and are animatable in uvs space (geometry). I will have to test this but if it works you could have your follicle as a base to parent or parent constrain any type of object to your curve.

I use motion paths to attach objects to curves. You can set the u parameter to place your object on the curve where you want it.
