I have a group of graphical assets contained in a custom subclass of FSlateWidgetStyle, with the brushes loaded from a SlateWidgetStyleAsset to allow the assets to be modified without touching code (for design teams to modify). However, while it works in uncooked builds, cooking the game for release presents the following error when the Style is loaded by the Slate code:
[2014.07.11-13.57.40:468][ 0]LogLinker:Warning: Unable to load package (../../../UCP/Content/Slate/Styles/DefaultUCPUIResourcesStyle.uasset). Package contains EditorOnly data which is not supported by the current build or vice versa.
Anyone aware of why this is being marked EditorOnly? Adding the containing folder to Always Cook doesn’t seem to affect it.
Our builds are being cooked as (Windows/Linux)NoEditor through the standalone UnrealFrontend.
