The Mesh Tiler Houdini Digital Asset (HDA) takes a collection of meshes which have been distributed on a planar surface (Doesn't need to be square) and make it tileable. This result then allows you to copy this new "tile", without getting any obvious seams. This is especially useful for baking down a tile you scatter a set of high-resolution meshes on. Or if you just want a nice tileable mesh. The user gets control over a couple of parameters, which allows the user to get their desired result. This basically allows for a workflow similar to Substance Designer, but then in 3D.
