hair.json -> blender file

[affromero]

Awesome work!
Do you happen to have a script that includes the hair color in the .blend file? If not, could you please share some insights on how to achieve that?
Thanks!

Hi @affromero ,

The data in hair.json contains the following:

melanin,
redness,
root_darkness_start,
root_darkness_end,
root_darkness_strength,

The melanin and redness correspond to the Melanin and MelaninRedness values of the Principled Hair BSDF in Blender.
The other 3 values correspond to a darkening of the roots expressed as added melanin starting from the root.
I made an image explaining where these values could plug in:
