Houdini Building Destruction

Simmed in Houdini 18, rendered with redshift.
Some test with the RBD material fracturing in Houdini 18, some of the fractures like the main walls are fractured by custom hda which I prefer to use . I think it can get better results and more faster than default fracture tools.
I just ignored the debris simulation and the bounce is not so nature, may be it need more test to get better result.
