Importing Houdini large scale RBD to Unreal process

Hello, what is the process to import a large scale destruction scene into unreal with close to 150,000 packed pieces?

I have tried, alembic, FBX , and VAT materials ,with no success. The FBX and alembic arnt working primarily because it is to heavy and Houdini ends up crashing , even for one frame.

Ideally I want to bring in the Houdini simulation points and then instance the fractured pieces onto those points so that it inherits the orient and transform values . This is how it is done in Houdini, I am wondering if I can do this in Unreal. Would someone be able to show me a good tutorial on how to do this ?

The VAT material seems promising but I haven’t got it to work properly no matter how closely I follow the tutorials online . Any advice is appreciated. Thank you!

anyone?
