For Modo user switching to Blender 2.8

[APEC]

As I already mentioned above.
Select edges and in “Crease” field type value, but read about values (link inside).

Summary

@APEC

To see weight on the edge - open ‘N’ panel ‘Item’ tab

but I highly recommend to reed this topic about matching visually values with other programs

Export to FBX with checkbox “Export Subdivision Surface”
