Trouble with hair duplicates sticking to dynamic objects :(


#1

Hello,

I’m having trouble with hair sticking to a dynamic object. I’m trying to create tennis balls that collide with each other. I have created the tennis ball, applied the hair to it, have run a physics simulation to mess it up and wrap it to the surface of the ball. Have then set the hair dynamics and disabled them to hold the current state.

I’ve then grouped the model and hair object into a null.

When this null group is copied and moved the hair moves further than the model. It doesn’t remain attached to the new copy. Really frusterating! I’ve attached some pics for reference.

Cheers

I can’t’ really much tell on the references pics.

Anyway regarding this:
When this null group is copied and moved the hair moves further than the model.

This means a double transform. Basically, you move the null, it moves the model and the hair (First transform) However, since the hair is attached to the model, moving the model itself also moves the hair (Second Transform).

The proper workflow would have a separate null for the hair. And don’t ever touch it. Ever!
