This is a quick tutorial on how polygon flow can effect cloth dynamics.

Step 1: On two separate layers, Create two boxes either on the “X” or “Z” axis.

Here is a quick example of polygon flow for the cloth geometry.



Step2: Subdivide (shift + d))the boxes three times to get this.



Step 3:
Take the first box and make some cuts in the geometry using your
favorite tool (Knife tool, Split, Add Edges, Edge Bevel, or even Reduce
Edges), make the cuts preferably diagonally.



Step 4:
Triple (shift + t) both boxes and select the top row of points. This
will be a selection set called “Fix” for the cloth dynamics.



Note: Selection Sets are made using the “S” in the vertex map area at the bottom of Modelr's interface.

Step5: Jump over to Layout, add the boxes to your scene, and make both layers cloth.

These are the settings used for both layers.



Note: there is an extra box with more cuts for demo purposes.

Step 6:
Calculate the Cloth Dynamics. The calculation is done and the mesh with
the cuts and random geometry tend to be more spread out. The more cuts
that pull diagonally on the mesh the more random the cloth will be.



This
effect may seem slight, but it will add a bit more realism to your
cloth effects. Varying your geometry can be used to complement the type
of deformation that is used for a better effect.

Happy Rendering!
