Problem

Description:

i have a probl with dynamics,

- make sphere

- add ortnatrix hair

- by default lenght is 50, so i cut it down to 1 (dont need a hair half of meter :) )

- add dynamics node, and press play!!!

 

as you can see the hair just freezes to the sphere (even with G -9.8)

Steps to Reproduce:

Hi Milroad,

Does it simulate OK with a longer length for you?

yes, but i have a feeling, when you change the lenght is like you changed the scale of scene??? And the hair is acting like you changed the scale of the scene...

also i notice that particle radius is making problem when its 0, i had to tweak it untill i got the proper hair movement, + in maya 16 when im in VP2 its not updating viewport?

 

cheers

When particle radius is 0 it is computed automatically from the scale of the object. Setting it to non-0 allows you to manually set particles scale.

Regarding viewport update, make sure you have your scene evaluation set to DG: https://ephere.com/plugins/autodesk/maya/ornatrix/docs/1/Guides_or_Hair_Update_Problems.html

thanks for reply, i already tried and its not working, when i cut down the lenght its still acting like whole scene is scaled down... When someone cut your hair, dynamic of your hair is still the 'same', as i already reply, i will make an video, explaing whats the general problem...

p.s.

what will happen if i have a character with 2 type of hair? One long and one short? 

me again :)

here is an video link, best to view it in full screen i made some comments at the bottom of maya

Thank you for the video, I can see the problems. I will try to reproduce them on my machine.
