Dwayne, a couple more questions, if I may.
1. The Unlink thing that you suggested for collections worked. I’m puzzled by what the unlinking actually does. It would seem that if you unlink the collection from the scene, then the instances would lose their geometry references that are contained inside. But that’s obviously not the case because the instances in my scene rendered properly. So if they can still be referenced, how does unlinking tell Blender not to display them? Is it because the Blender Viewport and the Blender Render reference the scene and not the individual data-blocks? (That’s my best guess, even though I barely comprehend data-blocks.)
2. Is there a simple way to understand the difference between collection instancing (Add>Collection Instance…) and object instancing (Object>Duplicate Linked)? Or a good reference I can study?
Thank you again!
