今天对一个书的模型加Rigidbody,

MeshiCollider用的是mesh非UNITY自带的

出现

Non-convex MeshCollider with non-kinematic Rigidbody is no longer supported in Unity 5.

并且碰撞不起作用

在面板中

勾选了convex就解决了

去官网一查

Convex

If enabled, this Mesh Collider will collide with other Mesh Colliders. Convex Mesh Colliders are limited to 255 triangles.

如果是BOX Collider则没这个选项
