The unit of these direction parameters is the number of rotations, with 360° (1 rotation) expressed as 1.00, in the same way as 3D rotation parameters. The following relationships apply in the example shown in the figure.

The fractional part of the setting after the decimal point corresponds to an angle 0 to 360°. If the fractional parts of two setting values are the same, the effect is the same even if the integral parts are different.

The integral part of a setting value is used when moving a light source with keyframes.

For example, when the longitude of a light source rotates in the clockwise direction from 0.88 (315°) to 0.12 (45°), it rotates in the counterclockwise direction (the angle grows smaller) if the above values are used. In this case, the value of the second keyframe can be set to 1.12 (330° + 45°).

KF1 = 0.88

KF2 = 0.12

User texture pattern

In the spotlighting function, a user generated texture pattern can now be selected for the pattern with which the light falls on the image surface.

To add a texture pattern, create a texture package from a bitmap file, and install it.

The installed texture pattern can be selected in the same way as the texture patterns provided by default.
