Magnus Larsson showed how the team used Unreal and Houdini to prepare some explosive sequences.
"The workflow would be to export selected geometry that environment artists have placed, and create a simulation from that. The challenge in that is to not make it look too much like regular Voronoi fracture, and to still be able to cut through complex geometry where hundreds of assets have been placed, intersect, are not water tight, and such," wrote Larsson. "To that end, I created a very big for loop setup in Houdini that does a different type of Booleans based on the incoming geometry and makes a decision what to keep and what to throw away, this way I was able to break up this complex geometry without having to rebuild the mesh from scratch to make the boolean operation to work."
