Parameters
width: width: Width of the inner region of the rod (X-axis).
height: height: Height of the inner region of the rod (Y-axis).
depth: depth: Depth of the inner region of the rod (Z-axis).
radius: radius: Radius of the corners of the inner rod box.
edge: edge: Thickness of the edge region.
scaleWidth: scaleWidth: Scale the width of the inner rod shape (X axis).
scaleHeight: scaleHeight: Scale the height of the inner rod shape (Y axis).
scaleDepth: scaleDepth: Scale the depth of the inner rod shape (Z axis).
left: left: Additional size of the left region (-X axis).
right: right: Additional size of the right region (+X axis).
bottom: bottom: Additional size of the bottom region (-Y axis).
top: top: Additional size of the top region (+Y axis).
back: back: Additional size of the back region (-Z axis).
front: front: Additional size of the frontal region (+Z axis).
leftEdge: leftEdge: When edge is > 0, this scales the left edge up or down (-x axis).
rightEdge: rightEdge: When edge is > 0, this scales the right edge up or down (+x axis).
bottomEdge: bottomEdge: When edge is > 0, this scales the bottom edge up or down (-y axis).
topEdge: topEdge: When edge is > 0, this scales the top edge up or down (+y axis).
backEdge: backEdge: When edge is > 0, this scales the back edge up or down (-z axis).
frontEdge: frontEdge: When edge is > 0, this scales the frontal edge up or down (+z axis).
density: density: How much effect the filter has (0-1).
invert: invert: Inverts the entire effect of the filter.
intensity: intensity: Multiplier for both the diffuse and specular result.
diffuse: diffuse: How much this light filter affects diffuse lighting.
specular: specular: How much this light filter affects specular lighting.
saturation: saturation: Saturation of the light before hitting the surface (0=greyscale,1=normal,>1=boosted colors).
falloff: falloff: Controls the transition from the core to the edge.
colorRamp: colorRamp: This is Optional. This sets the color gradient for the transition.
combineMode:
