Am I going about this the right way with adding seams?
I am having difficulty even just baking the high poly onto the Low poly.
Above each image is their own UV Unwrap.
Hey Gary! I'm going through your file and the seams seem fine. What you definitely need though is some beveling! On the high poly, try not to have any perfectly sharp edges. After that the next stage is to make a cage from the low poly as shown in the video. Good luck and keep us updated!
