Rigged pants move together? Hello, I'm new to rigging models clothing onto models, I can't figure out why both pant legs move together I've followed tutorials on how to rig clothing and did everything they did, but the issue is, the tutorials were for shirts, not pants. I can't find any tutorials for this nor any solutions, if anyone knows why this is happening please let me know, its driving me insane. I've been trying to deal with this for like 3 days now. Thank you
To complete this workflow using data transfer I recommend:

Check that armature modifier switched to weight:



Join this two parts (Ctrl+J):



Then apply Data transfer. In unknown reason, it doesn't works with armature even if it first. (maybe, it is because it doesn't grab original mesh from source object)



Then, finally, fix weights using weight paint mode.



Draw weight with needed bone selected.
