Instance Tool - Editing instances directly in editor viewport

As far as i know that the bug hasn’t been fixed yet. The workaround is that either avoid using mirrored asset with instancing or create an new HISMA for all mirrored assets (with mirror apply on HISMA but not instanced meshes).

It seems that part of the confusion comes from the fact the naming of converted actor is generated and hard to find in the scene outliner. I’ll add option to let user specific the naming of converted actors in future update.

It’s a renderer issue, log within UE-17458: Unreal Engine Issues and Bug Tracker (UE-17458). It’s current status is “Backlogged” so probably won’t be fixed in official release anytime soon. I fixed that in my own repository and will submit it to Epic as a pull request soon.
