Sets parameters for 3DS MAX's scanline renderer.
The rollout contains the following parameters:
Mapping: Clear to ignore material mapping information to speed up rendering for tests. Does not affect automatic reflections or environment maps.
Shadows: Clear to turn off rendering of cast shadows to speed up rendering for tests.
Auto Reflect/Refract & Mirrors: Ignores automatic reflection/refraction maps to speed up rendering for tests.
Force Wireframe: Set to render all surfaces in the scene as wireframes. You can choose the thickness of the wireframe in pixels (default is 1).
Anti-Aliasing: Anti-aliasing smoothes the jagged edges that occur along the edges of diagonal and curves lines when rendering. Turn off only when you are rendering test images and greater speed is more important than image quality.
Filter Maps: Turns on or off the filtering of mapped materials. Leave on unless you are making test renderings and want to speed up rendering time and save memory.
Pixel Size: Smoothes the edges of objects for broadcast-quality rendering. The range is between 1.0 and 2.0. You can set this up to 2.0 if you first set the Pixel-Size Limit option in the Rendering page of the Preferences dialog. 2.0 provides the best quality but slows down rendering. Use 2.0 only if the 1.5 setting is insufficient because it can cause artifacting.
You determine which objects have object motion blur applied to them by setting Object in the Motion Blur area of the Properties dialog for that object. Object motion blur blurs the object by creating multiple “time-slice” images of the object for each frame. It takes camera movement into account. Object motion blur is applied during the scanline rendering process.
Apply: Turns object motion blur on or off globally for the entire scene. Any objects that have their Object Motion Blur property set are rendered with motion blur.
Duration: Determines how long the "virtual shutter" is open. When this is set to 1.0, the virtual shutter is open for the entire duration between one frame and the next. Longer values produce more exaggerated effects.
Samples: Determines how many Duration Subdivision copies are sampled (maximum 16).
When Samples is less than Duration, random sampling within the duration occurs (which is why there might be a slight granular look to the motion blur). For example, if Duration Subdivision = 12 and Samples = 8, there are eight random samples out of 12 possible copies within each frame.
When Samples = Duration, there is no randomness (and if both numbers are at their maximum value (16), you get a dense result (which costs between 3-4 times the normal rendering time for that specific object).
If you want to obtain a smooth blur effect, use the maximum settings of 16/16. If you want to cut down rendering time, values of 12/12 will give you much smoother results than 16/12.
Because sampling happens within the duration, the Duration value always has to be less than or equal to Samples.
Duration Subdivision: Determines how many copies of each object are rendered within the Duration (maximum 16).
You determine which objects have image motion blur applied to them by setting Image in the Motion Blur area of the Properties dialog for that object. Image motion blur blurs the object by creating a smearing effect rather than multiple images. It takes camera movement into account. Image motion blur is applied after scanline rendering is complete.
Apply: Turns image motion blur on or off globally for the entire scene. Any objects that have their Image Motion Blur property set are rendered with motion blur.
Duration: Specifies how long the “virtual shutter” is open. When this is set to 1.0, the virtual shutter is open for the entire duration between one frame and the next. The higher the value, the greater the motion blur effect.
Apply to Environment Map: When set, image motion blur is applied to the environment map as well as to the objects in the scene. The effect is noticeable when the camera orbits.
The environment map should use Environment mapping: Spherical, Cylindrical, or Shrink-Wrap. The image motion blur effect doesn’t work with Screen-mapped environments.
Tip: When blurred objects overlap, blurring doesn't work correctly and there are gaps in the rendering. Because image motion blur is applied after rendering, it can't account for object overlap. To fix this problem, render each blurred object separately, to a different layer, and then composite the two layers using the Alpha Compositor in Video Post.
Note: Image motion blur doesn't work for NURBS objects that are animated so their tessellation (surface approximation) changes over time. This happens when sub-objects are animated independently of the top-level NURBS model.
Max Quadtree Depth: The default is 7 levels, and if you reduce this, it takes up less RAM (but more time) and if you increase it, it takes up much more RAM (but less time). The highest practical range is 78, and the lowest practical range is 45. In some cases, if ray-traced shadows provide an incorrect result, it helps to decrease the quadtree depth by a tick or two, but otherwise you probably won't want to adjust this parameter.
Rendering Iterations: Sets the number of inter-object reflections in non-flat automatic reflection maps. Although increasing this value can sometimes enhance image quality it also increases rendering time for reflections.
