How to collide hair with an object as hair is growing
Hi all,
I have hair growing (animating the length in the hair texture) off of a mesh and it is supposed to grow until it hits a surrounding object, then bounce away from it. A hair collider tag on the object is not doing anything and I’ve even reversed the normals on the collider but nothing.
Am I doing this correctly or might there be a different way?
Cheers,

don’t know it that can be done with hair, Length in the hair material grows the apparent length along the guide (much like animating the growth along a sweep) but it follows whatever the guide is already doing, it is not growing the guide. The length of the guides (Guides/Roots) can be set but not keyframed – I don’t see a way around that.
It would be possible to fake it with particles perhaps (emit from the mesh and put the particles in a Trail object to which you add a hair material to render) but that wouldn’t have hair dynamics to move the hair behind the ‘growing end’ as real hair would…
