Description

What happened?

As reported on the forum Adding a GeometryInstance with a RectangleOutlineGeometry to the scene as a Primitive with a default PerInstanceColorAppearance gives the following error:

DeveloperError: Appearance/Geometry mismatch. The appearance requires vertex shader attribute input 'compressedAttributes', which was not computed as part of the Geometry. Use the appearance's vertexFormat property when constructing the geometry.

See this Sandcastle example.

But vertexFormat is not an option for RectangleOutlineGeometry. In this case, the PerInstanceColorAppearance will work as long as it is initialized with the option flat: true. See this updated Sandcastle.

Reproduction steps

  1. Construct a GeometryInstance with a RectangleOutlineGeometry
  2. Add it to the scene with a default PerInstanceColorAppearance
