Dynamic Data Asset

Dynamic Data Asset is a Data Asset class for Unreal Engine whose variables show and hide themselves based on the values of other variables on the same asset. Give a weapon a Type of Melee or Ranged, and the fields that only mean something for one of them stop cluttering the other. The same setup works for quest objectives, status effects, dialogue entries, or anything else where one field decides what the rest mean.

Rules are authored once on the Blueprint variable and evaluated per instance, so two assets of the same class can show different fields. When you cook, properties whose conditions fail are cleared in the cooked copy only. Clearing an object reference also keeps that asset, its materials, and its textures out of the packaged build. Your editor values are never touched, and the cook behavior can be turned off in Project Settings.

Key features

• Conditions authored on the variable, right in the Blueprint editor

• Rules compare against a typed literal or another variable on the same asset

• Groups with per-rule and per-group AND/OR for compound logic

• Literals edited with the engine's own widgets: enums get a dropdown, vectors get spinboxes, references get an asset picker

• Failing properties are cleared at cook, so shipped assets carry no dead data

• Cleared object references keep their assets out of the packaged build

• Copy and paste a variable's whole condition set onto another variable

• Broken rules are listed in a panel warning, never silently applied

• Four Blueprint functions for editor tooling and pre-cook validation

• Supports UE 5.0 through 5.8
