Round Edges Enabled– Enables the Round Edges effect, which uses bump mapping to smooth out the edges of the geometry during render time.
Radius– Specify a radius (in world units) for the Round Edges effect. Since the actual geometry is not being changed and only the normals of the faces are affected, large values may produce undesirable effects.
Consider Same Object Only– When enabled, the rounded corners are produced only along edges that belong to the object, which has the attribute applied. When disabled, rounded corners are also produced along edges formed when the object with the attribute intersects other objects in the scene.
Corners– Choose which edges are considered in the calculation. Possible options are:
Convex and Concave– Considers all edges. Convex Only– Only applies Round Edges effect to edges with convex angles. Concave Only– Only applies Round Edges effect to edges with concave angles.

Override Preferences – When enabled, the parameters in this tab override the global preferences of the scene for the selected material.
Enable Preview – When disabled, the previews of the material in the Viewport and the Material Editor are disabled. The material is displayed in all black. This saves on processing power.
Enable Global Illumination – When disabled, global illumination is not calculated for the current material preview.
Quality – Determines the quality of the material previews. Higher values give more detail but slow down processing.
Editor Map Size – Determines the resolution of the material preview. If you have extra-detailed textures applied to the material, this option allows you to preview those textures in higher resolution at the preview step, without needing to render.
