I wanted to know what the prefered workflow is when using the plugin with a rig.

 

Any info whould be helpful.

If I try to rig a mesh with Ornatrix hair after the bind the hair guides jump. Happens on refrenced and non refrenced meshes.

Let me know if the first link doesn't fix your problem.

I am using setttings from both links.

The hair guides all seem to jump to the origine. Also If I groom the hair and change or edit a fur density map in the GuidesFrom MeshNode then the groom goes haywire and I loose all my settings. Is this expected behavior? Because I often need to tweak maps on the fly while grooming to get the correct look.

Hi Pixteur,

 

Do the hairs guides jump back to the straight original version?

I had the same problem with converting to maya nHair. The was around was to apply a curvesfromstrands node. Then the 'original' hairguides conform to the groomed mesh node.

Just an idea:)

I haven't seen them jump back at all. The whole edit guide hairs seems really fragile. 

 

The only way I was able to work was riggin my mesh first then do the ornatrix hair work. I'm usinging remember root positions in the GuidesFromMeshNode, that helps but if I find I need more guides or less and turn this off all my EditGuideShape work is lost...

Yes, the Edit Guides modifier depends that you establish your guides first, and then remember the root positions. It uses the order and count of the incoming guides.

Sounds like what you want to mask is not guides, but the hair. Use your mask inside HairFromGuides operator and you can tweak it at any point in the future.
