I am struggling with one problem for over 3 years and i finally decided to discuss it with someone. Long story short:

  1. I got an object lets say CASE
  2. I got another objects like BUTTONS
  3. I got a collection called ASSEMBLED PART which contains collection instances of both BUTTONS and CASE.

What i did is append the ASSEMLED PART in new file. Sometimes i want to change material of CASE or BUTTON... but i cannot.

The "source instance" live somewhere but i have no clue where. library.blend

with file append.blend

Sorry for such simple example. Life case scenario is much more complex - we are designing brackets, than each brackets gets instance of screw and caps, then we use those instances of "ready part" to build another bigger part...

https://we.tl/t-HLFTk1GosZ here is a link for both files.

Can You please help me with it?

Thank You so much!

I'm not sure how it happened that the original objects of the collection are invisible in the Outliner in View Layer mode, that said you can make them visible: Select the Scene Collection in the Outliner, open a new Outliner window, switch it to from View Layer mode to Blender File, open the Meshes folder, drag and drop the 4 meshes into the 3D scene and they will appear in your Outliner in View Layer mode, now you can do whatever change to the object:
