Instanced Object Details

An Unreal Engine editor plugin that improves the Details panel experience for instanced (EditInlineNew) UObject properties.

Out of the box, UE dumps every property from a Blueprint-derived instanced object into a flat, unorganized list — including internal properties you never want to edit on instances. This plugin fixes that.

Features

• Property filtering — automatically hides properties marked as DisableEditOnInstance, showing only what's actually relevant
• Category grouping — respects Category metadata (including |-delimited subcategories) and renders them as collapsible groups
• Browse to Blueprint — adds a button next to the class picker that navigates the Content Browser to the source Blueprint asset (only visible for BP-generated classes)
• Zero-config — drop the plugin into your project and it works immediately for all Instanced UObject properties. No setup, no base class changes, no boilerplate

Before / After

Before	After

Properties are filtered by editability flags, and grouped into collapsible categories.

Installation

1. Clone or download this repository into your project's Plugins/ directory:

   YourProject/
   └── Plugins/
       └── InstancedObjectDetails/
           ├── InstancedObjectDetails.uplugin
           └── Source/
   

2. Regenerate project files and build.
3. That's it — the plugin loads automatically at PostEngineInit.

How It Works

The plugin registers a custom IPropertyTypeCustomization with a targeted IPropertyTypeIdentifier that only matches FObjectPropertyBase properties carrying the CPF_InstancedReference flag. This means it won't interfere with regular object references — only instanced (inline-editable) ones.

Property filtering — each child property is checked for CPF_Edit and rejected if it has CPF_DisableEditOnInstance, which filters out properties that are only meant to be edited on the CDO.

Category tree — the Category meta string (e.g. "Combat|Damage") is parsed into segments and built into a tree of IDetailGroup nodes, preserving declaration order within each level.

Browse button — when the current value is a UBlueprintGeneratedClass, a small content-browser icon appears next to the class picker. Clicking it calls SyncBrowserToAssets on the originating Blueprint.

Compatibility

• Engine: UE 5.x (tested on 5.4–5.6, released on 5.6)
• Module type: Editor only — zero runtime overhead, not compiled into shipping builds
