Blenderチュートリアル　新ヘアーシステムで思い通りの髪型を作る裏技！！

The script introduces new features in Blender 3.3, specifically the Hair System with Hair Curves, and upcoming Hair Assets in version 3.5 that allow for easy manipulation of hairstyles and textures. It acknowledges the difficulty some users face in creating desired hairstyles with Hair Curves and proposes a tutorial on converting mesh hair objects to Hair Curves. The tutorial begins with downloading a Blender project file and setting up a simple hair mesh divided into three parts: Hair Main, Hair Front, and Hair Side. The script emphasizes the convenience of separating hair into different parts for easier texture adjustments.

The tutorial demonstrates how to convert a mesh hair object, Hair Main, into a Hair Curve. It details the process of selecting edges that represent hair strands, extending these selections to the tips, and separating them into a new object. The script then guides through a two-step conversion process: first, converting the mesh to a regular curve and then to a Hair Curve. It also covers adjusting the normal directions of the curve segments to ensure the correct orientation of hair roots and tips, which is crucial for realistic hair simulation.

The script explains how to set up Hair Curve properties, including attaching the Hair Curve to a face object and using various Hair Assets to adjust hair thickness, distribution, and length variation. It describes the process of creating a natural hair look by adjusting factors such as hair density, maximum and minimum thickness, and length randomization. Additionally, the tutorial covers the creation of a hair material with the Principled Hair BSDF shader, adjusting melanin levels, and adding color variations to achieve a specific hair color.

This section focuses on refining the hair details by adjusting the hair's clumping and length distribution to achieve a more natural look. The script introduces the use of additional Hair Assets like 'Clump Hair Curves' and 'Trim Hair Curves' to control hair clumping and length variation. It also covers the process of duplicating and adjusting the hair objects to match the front and side hair with the main hair, ensuring a cohesive and natural appearance across different hair sections.

The final part of the tutorial involves adding natural variations to the hair by duplicating the Hair Curves and adjusting their properties to create fine hairs that add to the hair's texture. The script guides through copying the adjustments to the front and side hair noise objects to maintain consistency across the hair model. It concludes with a review of the natural hair variations achieved and thanks the viewers for watching, promising to meet again in the next tutorial.
