Skinned Mesh Renderer component

The Skinned Mesh Renderer component renders a deformable mesh. Deformable meshes include skinned meshes (meshes that have bones and bind poses), meshes that have blend shapes, and meshes that run cloth simulation.

To render a regular mesh, use a Mesh Renderer and a Mesh Filter instead.

When you add a deformable mesh or a model with a deformable mesh to a scene, Unity adds a Skinned Mesh Renderer component to the resulting GameObject.

In C# code, the SkinnedMeshRenderer class represents a Skinned Mesh Renderer component. The SkinnedMeshRenderer class inherits much of its functionality from the Renderer class. As such, this component has a lot in common with other components that inherit from Renderer, such as Line Renderer, and Trail Renderer.

Troubleshooting Skinned Mesh Renderer visibility

Unity uses the mesh’s bounds to determine whether to render it. If the entire bounding volume is outside the view of any active Camera, Unity does not render the mesh.

In the case of a Skinned Mesh Renderer, its mesh bounds change as it deforms. Unity accounts for all animations present at import time when it calculates the maximum bounding volume, and uses this value to determine visibility; however, the following situations that occur after import might push vertices or bones outside of the maximum known bounds:

• 附加动画
• Changing the positions of bones from a script at runtime
• Using vertex shaders that change vertex positions
• 使用布娃娃

If this happens, Unity might not correctly determine the visibility of the mesh, and might fail to show it when expected.

In these cases, you can try either of the following solutions to fix the problem:

• Modify the bounds to match the maximum potential bounding volume of your mesh. Use this option if possible, because it is better for performance.
• Enable Update When Offscreen, so that Unity continues to calculate the mesh bounds at all times, even when the mesh is not visible. Use this option if performance is not a major concern, or if you can’t predict the size of your bounding volume (for example, if you use ragdolls).

材质

Materials 部分列出了此组件使用的所有材质。

注意：如果材质多于子网格，则 Unity 会使用剩余的每个材质逐一渲染最后一个子网格，使一个材质加在下一个材质之上。如果材质不是完全不透明的，则可以将不同的材质分层并创建有趣的视觉效果。但是，完全不透明的材质会覆盖之前的层，因此 Unity 应用于最后一个子网格的任何其他不透明材质都会对性能产生负面影响，但不会带来任何好处。
