Hi everyone, is there any know but about use Normalize Strand over the animation cache? I'm having some issues to render in farm where each frame is jittering the hair. The hair was simulated in houdini so I imported as alembic cache, so far is working fine. But when I use the Normalize Strand over it as the image below, it looks creat a new normalized strand when the hair change the shapes because the animation cache.

 

 

I can't show any video where this happens, but is there any way to workaround that?

 

Thank you

Hi,

The Normalize modifier is not intended to be used with animated hair. In this case, if you still want the overall effect of this modifier, you have to bake the results into an Edit Guides modifier before/when applying animation. See how here:

As you found out, the flickering happens because Normalize Strands is recomputed at every frame, so it normalizes the strands every frame, causing indesired movements.
