部分模型不具有物理特性 可以改用prop_physics/prop_physics_override试一下

另外如果模型不支持物理特性 那么prop_physics/prop_physics_override也是无效的

Google Translate:

Some models do not have physical properties. You can try prop_physics/prop_physics_override instead.

In addition, if the model does not support physical properties, prop_physics/prop_physics_override is also invalid.
