The blend file comes with a multiresolution modifier for the trex of 3 subdivisions,and with a Control Rig ,i also used a addon called Wiggle Bones for the bones in the neck,tail and leg,is used to make that effect of physics to the bones, they are not that really necessary if you want to animate and you can also delete them if you dont want to use the addon, i still did a tutorial on how to use addon,and a guide on how to use the rig,also a timelapse of the walk1anim so i can give you tips on how to use the rig, heres the link https://www.youtube.com/watch?v=eId0Y_r3XvQ ,anyways thats it ,hope you like it!
