Cannot use abc file for Hair Asset about com.unity.demoteam.hair HOT 6 CLOSED

Hi! Are you using blender for the alembic file as well? I'm wondering if this error only occur with blender exported file for else. We are considering to switch to Maya just to use Unity Strand Hair

Ya I am. I created the hair using blenders new hair system then convert it to the old partial system hair. Then exported it as an alembic file. It shows up in Unity when you use the curve render component on the curve game object, but gives errors when you try and use it as with the units new hair system

Hi there, and thank you for reporting! I pushed a fix for a regression that may be related to this issue. Please pull latest and see if that fixes the issue for you.

This fix works for me. Although I still can't see any alembic file when selecting Alembic Stream Player, it works when I drag and drop the file.
Thanks for the fix!

Same Problem here. I am using Blender 3.2 3.3 3.4 to make hair with particle system.
I've tried to skinned the object with bone, and tweak the export setting but none of these work.
If I directly drag and drop the abc file from project file into Hair Asset Alembic Asset pannel, following warning shows and no hair appear in scene

Discarding provided curve set due to incomplete (out of bounds) vertex data.
