A “material” represents a collection of properties and settings that, when applied through the use of a “shader” (a small program/subroutine that describes how the settings are used), describe how the geometry associated with a 3D object interacts with light and ultimately what the surface of that 3D object looks like when rendered.

DzRenderMgr::RenderPriority : renderPriority

The render priority for the material. Render priority controls the order in which materials are handled during a render. The higher the priority, the earlier the material will be handled. If several materials have the same render priority, those materials will be handled in an arbitrary order.

The render priority on all nodes that use this material (this will include the top-level skeleton node when dealing with figures) can automatically be set to match the material's new priority by calling enablePropagateRenderPriorityToNodes() with true before calling this method.

The default render priority is DzRenderMgr::RENDER_PRIORITY_NORMAL.

void : enablePropagateRenderPriorityToNodes( Boolean propagate )
