Reducing Hard Angle from default 88 to 75 ish
(Model Import Settings, under Advanced (under Generate Lightmap UVs))
Upping Pack Margin (Again Model Import Settings, under Advanced (under Generate Lightmap UVs). tried upping default 8 to 32
Upping Pushoff from default 0.0001 to 0.01 (LightMapParameters (Under Lighting window, Scene, General GI. Click on Default Parameters, and Create New. Click Edit to change)
Upping Scale in Lightmap for the object can help reduce seams
Upping baked resolution 80/120 started to remove seams between sections
