Hi I've gotten to about 10 minutes into the lesson 31 video and I've run into some problems. When I go to skin each feather unit, only that feather unit remains deformable and none of the other feathers I set up for deforming are deforming anymore. Also, it appears not all the vertices are moving along with the rest of the feathers. The other snag I've hit is it seems after I set the feathers to deform I lose the ability to deform the rest of the main body. Does anyone know how to fix any of these issues? Thanks
