I've been building my own character mesh and following the Lightning Boy Studios videos on Youtube to try to create my own toon shader/outliner. For the outliner, I'm using a solidify modifier with a black emission material and backface culling enabled. Everything was going fine until I added a few armature bones just to do a preliminary check on how the mesh would behave under animation. When I moved the armature, the main mesh followed the armature, but the solidify outliner didn't follow at all (see reference image). I'm using automatic weights for the armature. My solidify modifier has already been applied. When I go into weight painting, I can't seem to be able to apply weight to the outline. I'm not sur how to fix this issue to allow the outline to move with the rest of the toon-shaded mesh. Can anybody help me solve this?
