Hi Arrow, for sure this can be done in both ways. But depending on the size of the jetpack keep in mind that it is moving a bit with the wearer although it's rigid. For example if the pack is reaching from neck down to hips and is rigid then either you need the wearers bodyparts to keep stiff ... not possible to assure this ... or it has to be parented or conformed as ONE part to the breast for example ... that means is the breast is bending left or right the pack is going with breast and the hip-next part is swinging out. So in this scenario be sure that the straps are only fixed with the brest part, otherwise you get in trouble with them cutting into other figure parts. But this is doable without problems. If you will use a parented pack you need a backstrap for picking the pack or in my mind the better way with conforming you need to suppress the pack bending as such influenced by neighbor parts. I would use the pack (rigid) as the breast part inclusive it's front straps in this area and split the rest of straps according to their neighbor parts, e.g. abdomen, hip and might be even thigh (l/r). So the pack and first strap parts go with the figures breast (rigid) and the rest of the straps follow the other figure parts (bending and twisting). For a example of this look into this package from me on sharecg: http://www.sharecg.com/v/42781/gallery/11/Poser/S.H.A.D.O.-Uniforms-for-V4 . These are uniforms from an old tv show and as a new equipement a oxygen rescue helmet (seen on 2. info image on sharecg). This rescue stuff is consisting of the oxygen flask worn on the back of the figue (breast conformed) and this is also rigid and to hold this the strappings (abdomen,hip) are bending with the rest body parts. So this should be the same situation as you are looking for. Maybe even that you could use the cr2 as a donor for your jet pack. Good luck Jo
