Environment: The background color creates a solid alpha channel and interacts with 3D
projects, including blend modes and reflections. In the following images of the Canvas,
Reflection is turned on for the elliptical shape (in the shape’s Properties Inspector). In the
left image, the elliptical shape retains its original white color because Background is set to
Solid. In the right image, the pink background is reflected in the elliptical shape because
Background is set to Environment.
Motion Blur and Reflections controls
Below the General section of the Properties Inspector are two groups of controls that can affect
how your project looks when exported: Motion Blur and Reflections.
The Motion Blur controls simulate the effect a camera’s mechanical shutter has on a frame of film
or video when the camera or its subject is moving. In Motion, motion blur affects objects in your
project that are animated using behaviors or keyframes, creating more natural-looking motion in
your project, even though the animation is artificial. As with a camera, faster objects have more
blur; slower objects have less blur.
No motion blur Motion blur at 360° Motion blur at 180°
The Motion Blur section of the Properties Inspector has two settings:
•
Samples: Use this slider to set the number of subframes rendered per frame, where one frame
represents 360 degrees. Higher Samples values result in a higher-quality motion-blur effect,
but are more processor-intensive. The default Samples value is 8. The maximum possible value
is 256.
•
Shutter Angle: Use this slider to define the size of the motion blur that appears for animated
objects. Increasing the shutter angle increases the number of frames over which the shutter is
open.
