Membrane
The Membrane generator creates a sheer, animated sheet that appears to move
gracefully about in 3D space. The speed, start and end points, offset, brightness, and
color can be modified and animated. To expand the animation beyond the Canvas
borders, increase the Width and Height parameters in the Inspector.
Parameters in the Inspector
Speed: Sets the speed of movement of the sheet. Values range from 0 to 2.
Start 1-4: Sets the starting point for the sheet wave. Experiment with these controls to
find different wave shapes.
End 1-4: Sets the ending point for the sheet wave. Experiment with these controls to
find different wave shapes.
Offset: Sets the coordinates of the center of the sheet. Coordinates are calculated from
the center of your object, which is the coordinate origin.
Brightness: Sets the brightness of the sheet. Values range from 0 to 50.
Color: Picks the color of the lens flare. Use the disclosure triangle to display Red, Green,
Blue, and Alpha sliders for more precise color selection.
