The CGI Nerd shows how you can create piles of anything with Houdini quickly.

Stacking and creating piles are always super-useful in 3D, and with Side FX Houdini, the task is quite simple. This new tutorial by the CGI Nerd Alejandro Perez shows an easy way to make anything into piles.

The tutorial uses instances and simple rigid body simulations to simulate a pile of stuff.

A similar tutorial from Stormz shows how you can use the Bullet Solver in Houdini to simulate a debris pile rather than placing all the stuff manually.
