So I have set up several mannequins in my house, they all work except for the last two. I made them the exact same way as all the others, so is there a limit to how many mannequins you can have in a cell? Or is there anything that you all could think of to make them not work properly?

there's a couple of linked ref's and properties involved, i assume you double-checked these?

also, there's that old story going around about the mannequins having a bug that kicked in when, uhm, the trigger part iirc, is set in a 0?° z-rotation, which should supposedly go away if you just set that 0.01 higher or lower (which i never could confirm myself neither for mannequin triggers specifically nor for triggers in general, hence my sceptical undertone)

other than that, just delete the whole stuff, make 2 new copies of your working setups (all parts selected so links etc will take over) and there ya go...

Yea I double checked all the references, but I'll try just copying them all from a working mannequin I don't know why I didn't think of that before, thanks for the help!

Awesome suggestion on rotatng z. Worked perfectly thank you!
