Hair Limitations

毛发限制

Hair has the following limitations:

毛发有以下限制:

• Hair is a volumetric effect when the Standard Renderer is used, which means it offers flawed results when combined with other volumetric effects such as PyroCluster, volumetric Clouds in Advanced Render (Physical Sky), etc. 当使用标准渲染器时，毛发是一种体积效果，这意味着当与其他体积效果结合时，它会提供有缺陷的结果，如 PyroCluster，在高级渲染(物理天空)中的体积云等

• When used in conjunction with the Physical Renderer, you will not be able to take full advantage of the complete spectrum of Hair parameters (see 当与物理渲染器一起使用时，你将不能充分利用毛发参数的完整频谱(参见Hair and the Physical Renderer 毛发和物理渲染器).

• Photon Caustics does not work with Hair. 光子焦散不适用于毛发

• Infinite 无穷无尽 light sources will be treated as point lights when casting shadows. 当投射阴影时，光源将被视为点光源

• The Cinema 4D Display tag’s visibility does not work in conjunction with HAIR. Cinema 4D 显示标签的可见性不与 HAIR 一起工作

• Hair can on occasion be rendered with the 毛发有时可以用Render-Manager 渲染管理器 (in this case, render in the Picture Viewer). (在本例中，在图片查看器中呈现)

All of these limitations do not apply if you render the hair as polygons (render time and memory requirements will rise sharply). So, how is this done? Simply select a Hair type from the Type menu in the Hair object’s Generate tab. Before you do so, don’t forget to reduce the number of actual hairs.

如果您将毛发渲染为多边形，那么所有这些限制都不适用(渲染时间和内存需求将急剧上升)。那么，这是怎么做到的呢？简单地从 Hair 对象的 Generate 选项卡的 Type 菜单中选择一个 Hair Type。在这样做之前，不要忘记减少真正的毛发数量。
