    [TUTORIAL] Unreal Engine 4.25. Alembic Hair. Q&A Part 1. Official answers from community.

    Official answers from Epic Games (Unreal Community) to various questions about Alembic hair in Unreal Engine 4.25-26.

    In this video, I answer questions such as:

    - solve the problem with DOF / Motion Blur artifacts while rendering hair?
    - transfer color from Xgen / Ornatrix to Unreal Engine 4?
    - avoid problems with wool simulation during Bind to skeleton mesh?
    - export hair from Xgen in three ways using different scripts?
    - solve the problem with Backface Culling during Scale X = -1?
    - set up a shader and add texture render?
    - to flip the texture?
    - improve shadow rendering and hair/fur quality?
