Highlight entire root


So I am trying to select and highlight the entire mesh.

The link I am following is

Now the problem is that when I select a mesh I want to enable highlight layer in the root, that doesn’t seem to be possible. As there could be a group of meshes for an object and when clicked on any mesh the entire group should get a highlight layer

In this case, you have to loop through the children of your base mesh and add them to the layer too.

That’s what I have done for now. But isn’t that will increase my iterations and that can impact my render queue ?

You need to do this loop only a single time, so there won’t be any impact.

Now, it’s of course more time consuming to render 100 objects in the glow layer than a single one, but you can’t do anything about this if you need those 100 objects to glow.
