G9 Capes
Someone, somwwhere is working on a superhero suit for G9.
Capes - please learn from the mistakes of the past :) Superhero capes do not nessesarily follow the same rules as capes for nobles or wizards.
Capes should be varying lengths. Most hit at knee-height, Mid-thigh, mid-calf, and ankle. (The Captain Marvel cape is a double-outlier, being shorter and attached differently than almost anyone elses)
Capes are most typically of two types: Superman, which depends from the shoulders, and Batman, which is joined at the front.
People keep insisting that capes have these massive clasps, which typically they do not.
dForce - you can just not bother. Again, we're not talking capes for noblemen or opera cloals or something. Capes need to hang flat, AND have several morphs for billowing, flowing, moving out behind and above the character. It needs several places to bend, fold, twist, etc.
Capes also need to adjust for the back. AFAIK only ONE product ever bothered to look at the problem of clipping against the back:
