OGLVertexColorOverlayShader (object)

バージョン 1.12.0 で追加.

The OGLVertexColorOverlayShader is used for rendering surface attributes as a semitransparent colored overlay on top of existing geometry. It offsets the overlay geometry in the -Z space to ensure no z-fighting occurs between the underlying geometry and the overlay.

This shader is often used to display multi-channel maps over the top of geometry in the viewport.
