I have tried doing this three times over. The first time I just forgot to add the second modiefier that Mike mentions at 2:34 minutes of the video. Then I renamed my bones, reset my transformations, applied rest pose joined meshes from bottom to top, made sure my animation was at 0, did EVERYTHING. Nothing helps. The rig stands alone at the edge of the lattice and the lamp is in the middle as soona s I unparent it. Reparenting doesn’t help.
I moved my model to 0,0,0 position and cleared all rotations. I moved my model up on Z by 0.23 so that it would fit the rig. Then finally the rig worked and the model moved with it. After this I played my animation and it worked but the rig still stood alone and unmoving at the edge of the lattice, locked in rest pose.
I set the rig free to pose mode and played the animation. -sigh- The animation exploded in my face.
Could this be a point of origin -thing? Maybe my lamp wasn’t at 0,0,0 when I began constructing it? I don’t remember when I moved it. I think I did the base and then moved that.
Anyway, for me the rig needs to be exactly on top of the lamp to work and even then the animation doesn’t work.
