I am working on creating a ground shatter for my student project .in this scene i have created two layers of floor the top one is layer of floor tiles with bigger pieces and the layer below it is of cement with smaller pieces what i want to do is cache the lower layer as a bgeo and then use the bgeo to break the upper layer ,but i cannot figure out a way to do so .what is that i am missing here like which parameter can allow me to do so.

While I am not exactly sure of your complete issue, to answer the question posed in the title of this post, "How to use .bgeo sequence as a collision object", it's straigtforward.

 

Write your .bgeo disk.

Read them back into Houdini with a file SOP. 

Create an RBD static object in your DOP network using the file SOP as it's source. 

Toggle on "use deforming geometry" on the static object DOP. 

You'll now have an animating static object based on your .bgeo cache in your DOP network which you may use for collisions.
