4.13 preview Highlight broken

When editing a mesh with a multi material (Element 0, 1, etc), the ‘highlight’ option doesn’t work anymore. The other option ‘Isolate’ still works fine.

Hello Maxbrown,

I was able to highlight and isolate individual elements on my end. Can you reproduce this bug in a blank project? If so could you provide the exact steps you took to reach this issue?

Thank you for your time,

Hi Ed,
I just tested in 4.13.0 prev2. The issue for me is still there. Tested in blank and existing project:

  1. import fbx containing object with multiple materials (from Blender)
  2. edit the asset
  3. use checkbox ‘isolate’ works fine
  4. use checkbox ‘highlight’ doesn’t show any color (like it used to in 4.12 and before)

After some research I found that this issue has already been reported, you can find the Public JIRA here: Unreal Engine Issues and Bug Tracker (UE-33414)

Strangely enough some assets don’t seem to be affected by this issue. I have no idea why that is currently but in the meant time you can track the bug to see if it has been fixed.

Thank you for submitting this post!

I also find that this is broken in 4.13.1.

It seems to be related to enabling/disabling of post-processing in the static mesh editor.
It works for me if I turn post-processing off in the preview settings window.

I tried this with the basic shapes (Cone, Cylinder, Cube) in the Engine/Content/BasicShapes folder.

I’ve updated the Bug report with this information to assist the developers. Thank you for posting your findings!
