Creating a character to do an animation but have been very unsuccessful in getting clothes to act like they are on the character. Created him in Make Human. Exported with just s shirt on so I could use that to make his robe/gown. Copied shirt and created gown. Tried many videos and even though none were that similar to mine I tried them all and it partially works when gimbal moves. Anyone else make and rig clothes in similar manner?
Look up weight painting, its much more intuitive than creating vertex groups. I would recommend DanPro's videos at Youtube. They are based on Rigify, but the weight paint section applies.
Also, there is an issue with importing, since the character's default position is lying in his back. Most 3d programs use the y axis as up/down, but Blender uses Z axis. See if your importer has a setting to make up for that.
