Tutorial 2 follows from the end point of Tutorial 1 - Building
A Flow. Please load the Flow from the previous tutorial.
If the Large View is not currently open, press F5 to open it.
Adjust the proportions of the Large View to the Flow area by
dragging the splitter bar between them.
Drag and drop a Highlight tool (HiL) between Loader 2 and Merge
1. Notice the different cursor icons and how the Flow is moved
over to make room for the new tool. The inputs and outputs of
the tools are automatically connected. The Highlight tool will
only effect Loader 2's image because Loader 2 is the only tool
before the Highlight tool. Anything that comes after it will
be affected by it.
the Highlight tool on the Large View and Merge 2 on the Small.
View different tools on different views at the same time.
Expand the Highlight's Control Header to reveal the controls.
There are two tabs that organize the controls into related groups.
The Settings tab should be visible by default. Slide the High/Low
range slider to the left a bit and notice the effect it has
on the image. (Fig 1) The Highlight tool adds a star filter
effect to a select range of pixels based on their luminance.
A range slider represents a range of values, rather than a single
value. Modify the range by dragging the endpoints of the slider
the entire length of the slider or by entering values into the
Drag the left edge of the range slider to the left. Notice how
the Highlight tools' effect increases. This is because the range's
effectiveness responds to pixels with lower intensities. Pixels
that have intensities greater than the right edge of the range
receive the full effect of the tool. Set the low range to 0.65
and the high range to 0.85.
The Curve slider adjusts the falloff of the effect. Slide it
left and right to change the Highlight effect. Experiment, then
set the Curve value to 0.0. There should be some stars that
cast lightly colored rays.
The Length slider determines the length of the rays produced
by the tool. Sliding this control all of the way to the right
may produce extreme results. Set this value to 0.65
The Number of Points slider sets the number of rays emitted
by the tool. Set this to 7.
Look at the Angle control. This screw is used to represent a
control that has no set high or low values. This means that
it can turn indefinitely in either direction. This controls
the angle of the rays produced by the tool. Drag it left or
right for the desired angle.
Select the Color Scale tab to view the additional Highlight
controls. (Figure 2) The Red Scale, Green Scale and Blue Scale
sliders adjust the color of the effect. The Alpha Scale slider
controls the transparency of the highlights. Set these to R=0.75
G=0.9 B=1.0. This will give most highlights a cool blue tint.
Set the current time to 0. Return to the Settings tab of the
Highlight tool. Right click on the Angle screw and select Bezier
Spline. (Figure 3) Click and drag the screw to about 180. Move
the current time to 135 and drag the screw to about 0. This
has animated the Angle screw between frame 0 and frame 135.
Drag the Time Slider to the beginning of the scene. Notice how
the Angle screw moves as well. Set the beginning and ending
key frames of the Angle screw, and Digital Fusion has animated
all of the in-between frames.
Drag and drop a Glow (Glo) tool to the right of Loader 1. This
will only affect the planets of Loader 1. Set the Current Time
to 120 and view the Glow on the Large View.
The Glow tool adds a luminous diffused glow to images. Expand
the Glow Control Header. The Glow Size slider determines the
size and intensity of the glow effect. In this case, it controls
the size of the planet's haze. Drag it to the maximum of 100.
The glow now appears to be bright over the surface of the planets
but dark around the edges of them. This is because the Subtractive/Additive
slider of Merge 1 is set all of the way to Subtractive. Set
it to additive to increase the glow around the planets.
Select the DFX tab on Glow 1. The Blend slider controls the
blend between the original image coming into the tool and the
effected image. Set this to 0.3
The Glow slider controls the curve, or gamma, of the effect.
In this tool, it brightens/darkens the haze around the planets.
Set it to 0.75.
SAVE. Select Merge 2 and right click on it. Select Create Preview
and create it on the Small View to display the results of the
tutorial. Make sure to set the render ranges first!
