If you want to get a skin from a website like https://mineskin.org/, simply copy the 'Texture Data' field and paste it into the Skin.Value field in the recording file located in plugins -> MotionCaptureRewritten -> Recordings. If the Skin.Value field does not exist then please use the /mc skin, command to generate this field.
Next copy the 'Texture Signature' field into the Skin.Signature field. Same thing applies as with the Skin.Value field.
Now your skin will appear!
Added the /mc remoteReplay, command. This command allows you to replay the recording for another player.
