Attribute Profile

An Attribute Profile is the Content-Browser asset that registers a custom lane attribute (a URoadLaneAttributeDescriptor Blueprint). Once created, the new attribute type appears automatically in Attribute Mode — no changes to the core plugin.

Creating one

From the Content Browser: right-click → Meta Road → Attribute Profile, then choose the base class the profile derives from:

The base classes are the Generate Attributes family — Spline Mesh, Component Template, Actor Template, or Lofting (Pro). Pick the one that matches what you want to place along the lane (each has its own page under Attribute Types with the full field reference), or subclass the Generate base directly to emit custom geometry from GenerateAsset().

How it’s used

The new attribute type appears automatically in the Attribute Mode attribute tree — add it to a lane and place keys like any other attribute. You can also drag the profile asset from the Content Browser onto a road lane to add it directly (see Profiles → Drag and drop).
