Reply To: i have downloaded 2.80 _exercise_ 11 but cant see stomp in the view port .PFA link for reference

The collections that you link in are the names you see.

STOMP is the master collection
Stomp_GEO is the collection that holds the geometry (mesh)

You want to Link in the master collection (STOMP)

and then make a proxy of the rig (so you can move the geo).  That is called “Stomp_rig”.

None of this is simple, it’s 3d art after all, but once you get your head around it, it will become second nature.
