Add a K-DOP collision hull to a Static Mesh

Steps

There are a series of menu options in the Static Mesh Editor under the Collision menu entry, named ##DOP, these are the K-DOP simple collision generators. K-DOP is a type of bounding volume, which stands for K discrete oriented polytope (where K is the number of axis aligned planes). Basically it takes K axis-aligned planes and pushes them as close to the mesh as it can. The resulting shape is used as a collision hull. In the Static Mesh Editor K can be:

  • 10 - Box with 4 edges beveled - you can choose X- Y- or Z-aligned edges.

  • 18 - Box with all edges beveled.

  • 26 - Box with all edges and corners beveled.

See below for an example. This tool is quite handy for packages full of pipes, pillars, and railings:
