If Golaem Editors don't show, start by checking the Unreal Engine Output Log for errors. If an exception saying "No Qt binding were found" pops, it means that Qt For Python (PySide) is not installed or has not been installed properly. For the Golaem Editors to work properly, some third party dependencies need to be manually installed, especially Qt For Python. Please check the Install Dependencies part of the documentation.

If Characters are not at the expected size within Unreal, that usually means the Golaem Crowd Unit is not set up properly. As it also influences Unreal character bounding boxes, it could make them flicker in the viewport as well. Please check the Setting up the Scene Unit part of the documentation.
