Refresh Model Preview

Questions & Answers
1

I have a type of object with a custom inspector that will add or remove children, modifying what the object as a whole looks like. This works perfectly in the hierarchy when I can see those changes in the scene view, but in the inspector view if I want to see those changes in the preview window I have to deselect the object and select it again (which is tedious.)

Is there some way to force the inspector to re-draw that preview window as if the object had been re-selected?

Things I’ve tried :
Calling Repaint(); after modifying those objects.
Calling EditorUtility.SetDirty(myObject); after modifying those objects

Tried implementing OnPreviewGui() as well but I couldn’t really get it to do anything I wanted to do.

Anyone have any tips on this?

EDIT : Heres an image that will hopefully make it clearer what I’m trying to do. I need to refresh that model preview at the bottom whenever the preview or clear buttons are pressed.

Well I solved this in a pretty ugly way, essentially what it does now is if a button is clicked it tells one of its children temporarily to swap focus back to it if that child becomes selected, and then it forces that child to be selected. The result is you get a screen flicker but ultimately you end up selecting the same object you were selecting with all the same data, but the preview window is updated.

If someone can come along with a better answer though that would be amazing.
