• Question 13:

  What will a Dmap shadow do that a Raytrace Shadow will not?

  A Dmap shadow will...

  A. be visible in an IPR

  B. create volumetric shadows through a light fog

  C. produces correct shadows from transparent colored surfaces

  D. produces correct shadows from Cloud Render Type particles

  Correct Answer: B

• Question 14:

  Which statement is most accurate?

  DmapAutofocus...

  A. adjusts the size of the square grid of pixels that's placed in front of the light for the first pass Raytrace Shadow calculation

  B. is the attribute that controls the focal point used in depth of field calculation

  C. controls the shadow anti-aliasing level used for the Raytrace Shadow calculation

  D. is the attribute that automatically controls where the Dmap will be focused.

  Correct Answer: B

  Explanation: Autodesks Official Answer: If on, Maya automatically scales the depth map so that it only fills the area of the light's illumination that contains shadow casting objects. For example, if shadow casting objects are only in the center of a spot light's beam, the depth map only covers the region occupied by those objects. Because the Resolution is an absolute resolution (that is, pixels, not pixels per inch), decreasing the size of the depth map effectively increases the resolution of the depth map and the quality of the shadows without increasing rendering times. If off, you can manually scale the depth map within the area of the light's illumination using the Focus attribute (for point lights and spot lights) or the Width Focus attribute (for directional lights). Use Auto Focus is on by default.

• Question 16:

  What effect does the Break Tangent action have on a selected animation tangent?

  A. Allows manipulation of the in and out tangent handles individually so you can edit the curve segment entering or exiting the key without affecting its opposite handle.

  B. Causes the manipulation of an in or out tangent handle to affect its opposite handle equally

  C. Specifies that when you move a tangent, only its angle can be changed.

  D. Specifies that when you move a tangent its angle and weight can be changed.

  Correct Answer: A
