It happened again, but during a different operation: I was working on a hip morph for V4, while at the same time adjusting weight maps to make the morph work nicely with the weight maps. After some time I noticed that once again, every bloody parameter dial was turned visible - but this time, in the hip actor only. So something along the way must have triggered that: - created a temporary group in the hip, applied a magnet to it, spawned a morph target. - deleted the temporary group, then continued working on that morph with the morph brush. - edited the weight maps in both thighs (side-side movement) - switched to and fro between editing weight maps and the morph. - used the group editor a couple of times to flip the normals of the hip - used the "mirror morph" command frequently. At some time along all these operations, the hidden morph dials must have been set to "hidden 0" So I'd suggest that SM checks each occurrence of "hidden 0" in the code, and investigate. Since, to my knowledge, there is no way to set a dial visible/invisible from within the program at user level, any occurrence of "hidden 0" shouldn't be there except for newly spawned dials (and only for this dial). Cheers
