Here is the simple network for the laces. I placed curve points only on the eyelets of the boot and various points wrapping around the top of the boot. Once I was happy with the placemement, I added more points to get the exact shape that was needed for the boot. The laces were tied with the same curve by hand. I could not find a procedrual way to tie a knot.
My next step is to bring it into ZBrush and add stitching detail and treads. I will then bring it back to Houdini, create a low poly using the Topobuihe Games Baker ROP is part of the Houdini Game Development Toolset that can be found on GitHub here: https://github.com/sideeffects/GameDevelopmentToolset
Once I get a good normal map, material ID, curvature, ambient occlusion, and roughness map it will be exported to Substance Painter.
