Hidden datasmith assets get automatically unhidden in the outliner when reopening a file. How to keep them hidden?

Development Getting Started & Setup

Hello,

I am new to UE.
After some testing I was able to import a .step file (cad file type) into UE5.1.
It has some parts in it I want to remain hidden but which I don’t want to delete.
So, I uncheck the eye in the Outliner and save the file.
When I reopen this file all hidden eye icons are unhidden again.
The same happens when I create layers to have the parts hidden that I want to hide but there the same happens; a shut-eye doesn’t remain a shut-eye.

What am I doing wrong and what should I do to prevent this?

Thanks so much, Per

Hi!

The unhiding of previously hidden objects is a thing that Unreal (annoyingly) does. This basically functions as a temporary hide functionality.
What you can do is in the “Rendering” tab in your object, untick the “Visible” parameter. This will, well, make it invisible.

Hopefully that solves your use case!
