everyone, I am trying to add rigid body properties to a mesh model in Blender. There are a lot of tutorials available on how to set rigid body property of the Blender built-in mesh models such as cube. I followed this tutorial to do the same thing in a imported mesh model.

However the weird thing is that the built-in cube falls normally on the passive plane but the imported mesh model just falls through the passive plane. Is there anything special to be set in order to make the imported mesh also work normally?

Thanks very much. I put on blender file here and I use Blender 2.79 on windows 10. I am sorry that the file size is large since the imported mesh model is very large.

Eventually I figured it out. It turns out that the mesh model is too complicated. I need to first use the Decimate Modifier to simplify it. Then it works normally, although with some vibrating effect.
