There are many ways. You did not mention if the hotspot you are talking about are in 2D or 3D, nor if you scripted the object in GDL, or just saved it from the 3D window.
As you appears a bit lost, I suspect you are not familiar with the GDL commands, so for you can be a bit hard to add the correct HOTSPOT statements, to get the black nodes where you need them.
here a workaround... (you need to re-create the object from the original 3D elements)
-- Use some very simple object to "mark" the places where you want the hotspot. For example you can use the "Sphere" object from the standard library.
-- Save the whole object, including the spheres.
-- Open the new object (File/Library and Objects/Open Object)
-- Go to the 3D script (using the buttons on the left)
-- Browse the text, and search for the lines starting with
CALL "Sphere" ...
-- Replace the whole command with
HOTSPOT 0,0,0, unid: unid=unid+1
-- Remember that the CALL command is NOT just one line. I can't check right now, but you need to delete all the lines ending with a comma (,)
-- You have to replace all the CALL "sphere" commands with the HOTSPOT commands, one for each sphere object you placed.
-- Save the object and check... if you are lucky it will work as you expect.
Maybe I am been not so clear in my explanation... ask if you need more detailed instructions.
