There are steps in this video that are not the most optimal way of doing things, at the pace programs update these days this process may change. Was trying to do my part on putting out some information out there that might someone may find useful but I was trying out some character pipeline's between UE4 and Houdini as this is a program I am pushing on lately for learning.
Here is a link to a very helpful channel that first got me into the investigation of the character pipeline. https://www.youtube.com/channel/UC65D7DvzyyGEqIJVxK-XhDg
