The Renderer panel includes settings for optimizing mental ray rendering as well as controls for camera effects, shadows, and displacement shading.
The Global Tuning Parameters parameters give you high-level control of the quality of mental ray shaders for soft shadows, glossy reflections, and glossy refractions. These controls let you adjust overall rendering quality without having to modify individual light and material settings. In general, lowering a global tuning parameter value decreases rendering time, and raising it increases rendering time.
The controls on this rollout affect how the mental ray renderer performs sampling for antialiasing rendered images.
The controls in this rollout let you choose whether to render using ray-tracing, scanline rendering, or both. You can also choose the method used to accelerate ray-tracing.
The controls in this rollout are for the camera effects depth of field and motion blur, as well as for contour shading and adding camera shaders.
The controls in this rollout affect shadows and displacement.
