As you might have noticed in the previous Intelligence Bulletins Reto.Mato has been hard at work expanding our character pipeline and building new parachutes. Here is a bit more information on how this process works. Enjoy! – Reto.Robotron3000

When creating the uniforms for the characters, we start out using a cloth simulation program to create the base uniforms cloth pieces draped over a body model. This creates realistic looking folds and wrinkles on the uniforms. We decided to make a parachute bag with it’s intricate straps and the open parachute canopy itself in this cloth simulation program. We wanted to see if we could benefit from the simulated forces from the pulling of straps, ropes and the effects of wind and gravity. The simulation for the bag and the straps is made on top of the German paratrooper uniform for a perfect match.

To create the parachute bag in the cloth simulation program, each piece of cloth geometry is made just as a flat piece of real cloth laid out on a tailor’s table. These pieces are then meticulously sewn together, edge border seams and internal seam lines are created and then real world material properties like canvas, wool or leather are applied. Once all the pieces are done they are arranged in 3D space in roughly the right position in relation to each other and the uniformed model they need to be draped upon. The first test simulation is run. This will show if corrections to the various cloth pieces are needed in order to make a nice tailored fit to the underlying uniform below. Once everything looks nice, the particle count of the cloth is set to maximum to get the highest detail possible and the simulation is run for the final time. This high resolution model is then sent to a 3D sculpting program called ZBrush, where additional modelling and tweaks are made to fit 3D models of buckles, hooks, ropes, buttons and belt loops.

The open parachute canopy was made in a similar way to the bag. Again each individual pieces was sown together and ropes was added to the cloth’s end pieces. In the opposite end, the ropes was attached to a set of straps next to the body model. Pressure was added to the chute to “blow it up” and pulling it up into the air while the ropes was preventing it from flying away.

Happy skydiving! :o)
