Hi everyone,
sorry again for my english..

i try to use hair system.
But i have a problem with guidegroom, if i apply a hairclump node into guidgroom node, i can see that my guide are not stable, they are not fixed on my point, he turn around his axis.
I attach an example for show you.

There is a solution for stabilize my guide and he turn never?
I want my guide dont move if i transforme my geometry, i want he stay stable.

Please, say me if i'm not understable, thank you.

Bests regards

Hi, the reason your guides are doing that is because you are scattering onto an animated surface. I've uploaded a hip file and screenshot showing how you can use a rest position and guide deform.

ie.
The non-animated sphere (before the transform node) is rest geometry you use to create guides.
The animated sphere (after the transform node) is the geometry you use to deform the guides.

EDIT: Or you could just use a Rest sop before the Transform instead of the guide deform.
