Quick Strap - Draw and Simulate Straps & Ropes

hodgson3d in Modeling


Quick Strap lets you draw rope, straps, spiral straps, and insulation that wrap around your objects in a physically accurate way. You can even layer cloth simulation ontop of your wraps to ensure the most physically accurate results possible.

Strap Creation:

All three tools build straps from simple cross-section lines you draw across your mesh: Single turns one line into a band/rope hugging your object, while Spiral and Insulation use two lines to coil a winding strap or sheathe the geometry between them in a tube. Users can adjust settings such as surface offset, width, curve de-intersection

Simulation:

Add your straps to the simulation list and Quick Strap handles the setup for you — cloth physics, collision, and self-collision are configured automatically. Hit Play to watch the straps cinch tight around your geometry Dial in the shrink and sewing force to control how firmly they pull, create stitches to bind separate edges together. When you're happy, bake the result with a single click.
If you need to tighten your straps during simulation you have 2 options:

  1. Delete some faces to create a gap in the strap and use the 'Create Stitch' Tool to cinch the straps back together. In essense, shortening the straps so they wrap tighter.
  2. Alternatively you can increase the shrink factor which will tighten them but this will also shrink your straps so best to keep this value low to ensure the width of the straps stays consistent. 


Hero Geometry Tools:

  • Curve Deform fits or arrays a hero strap along your curves. It includes controls to either deform the geometry smoothly along the curve or instance it (for building chains and the like). You can twist the geometry incrementally and align its tilt to a target mesh when needed.


  • Create UV Mesh automatically unwraps and quadrifies the strap's UVs and flattens it in world space, so you can use the Surface Deform modifier on your hero geometry, bind it, and have it follow along with the simulated straps by adjusting the geometry nodes modifier factor to blend between shapes.
