Rich documentation inside graphs
Graph Comments adds a rich Markdown body to native Blueprint and Material comments while keeping a separate plain-text title. Documentation stays alongside the graph logic it explains.
Supported content
Section titled “Supported content”Comment bodies support tables, task lists, highlighted code, images, links, footnotes, collapsible sections, mathematical notation, and offline Mermaid diagrams.
Use the title for a short description of the graph section and the body for behavior, assumptions, examples, and maintenance notes. A diagram can describe a sequence or relationship without moving that explanation away from the graph.
Editing
Section titled “Editing”Edit documentation through Details or directly on the graph using Shift-click. Edits support live updates and undo.
This gives the same comment both a compact graph title and room for a longer explanation when the reader needs it.
Unreal asset references
Section titled “Unreal asset references”Unreal asset references provide thumbnails, navigation, and supported previews. Media playback requires explicit activation.
Asset references in a comment remain documentation links. They do not automatically create cooking or migration dependencies. If an asset is required by the application at runtime, manage that dependency through the project’s normal asset workflow.
A useful graph note
Section titled “A useful graph note”Document the graph’s purpose, its expected inputs and outputs, and any assumption that would be hard to infer from the nodes alone. Link a related Unreal asset when a reader needs to inspect it, and use a table or diagram when that makes the relationship clearer.
Use Quick Shot when the documented graph also needs to be shared as an image.
