Hello,
Well, I'm not sure to see a problem in what you describe, but I may not fully understand your point.
Just to make things clear, I've written a small script you can copy/paste in the console:
import Render
doc = App.newDocument()
# Create a part
cube = doc.addObject("Part::Box","Box")
cube.Label = "Cube"
# Create a link
link = doc.addObject('App::Link','Link')
link.setLink(cube)
link.Label = "CubeLink"
link.Placement.translate(App.Vector(15, 0, 0))
doc.recompute()
# Place point of view
Gui.activeView().viewDefaultOrientation()
Gui.runCommand('Std_PerspectiveCamera', 1)
# Create a Render Project (select your own renderer)
proj, _, _ = Render.Project.create(doc, renderer="Ospray", template="ospray_studio_light.sg")
# proj, _, _ = Render.Project.create(doc, renderer="Povray", template="povray_studio_light.pov")
# proj, _, _ = Render.Project.create(doc, renderer="Cycles", template="cycles_studio_light.xml")
# Add views
proj.add_view(cube)
proj.add_view(link)
# Render
proj.render()Do we agree that, with such a script, we expect to see 2 cubes in the rendering (the original and the link)?

There is not one „std part“ in your example at all, so this script does not produce the problem. Try this:
import Render
doc = App.newDocument()
# Create a std part
part = doc.addObject('App::Part','Part')
part.Label = "std part"
cube = doc.addObject("Part::Box","Box")
cube.Label = "Cube"
part.addObject(cube)
# Create a link
link = doc.addObject('App::Link','Link')
link.setLink(part)
link.Label = "std part link"
link.Placement.translate(App.Vector(15, 0, 0))
doc.recompute()
# Place point of view
Gui.activeView().viewDefaultOrientation()
Gui.runCommand('Std_PerspectiveCamera', 1)
# Create a Render Project (select your own renderer)
# proj, _, _ = Render.Project.create(doc, renderer="Ospray", template="ospray_studio_light.sg")
# proj, _, _ = Render.Project.create(doc, renderer="Povray", template="povray_studio_light.pov")
proj, _, _ = Render.Project.create(doc, renderer="Cycles", template="cycles_studio_light.xml")
# Add views
proj.add_view(part)
proj.add_view(link)
# Render
proj.render()Edit:
Result looks like this:

OK, thank you, this is clearer, I'm gonna investigate.

Fine.
To get the second problem, comment the proj.add_view(part) out. The part is rendered even it has not been added…

Yes, you're right. Actually, the 'std part link' object has got a Group property, pointing to the underlying Cube. In such case, it is not clear for me how to handle it precisely: create views for all components + container, or for container only (I've already encountered both cases...).
Seems that 'links to App::part' should follow the second behaviour (container only), whereas they are currently defaulted to first one. I'm gonna fix it...
