BumpBoss

BumpBoss produces an emboss effect by overlaying input A over input B, rather than offsetting a single input image like the Emboss node. The BumpBoss properties can be modified by the offset between the center and lightposition indicators in the Viewer.

Inputs and Controls

Connection Type	Connection Name	Function
Input	A	The emboss texture to overlay input B.
	B	The image sequence to emboss with input A.
	mask	An optional image to use as a mask. By default, the filter effect is limited to the non-black areas of the mask. At first, the mask input appears as triangle on the right side of the node, but when you drag it, it turns into an arrow labeled mask. If you cannot see the mask input, ensure that the mask control is disabled or set to none.

Control (UI)	Knob (Scripting)	Default Value	Function
BumpBoss Tab
channels	channels	all	The emboss effect is only applied to these channels. If you set this to something other than all or none, you can use the checkboxes on the right to select individual channels.
light position xy	lightposition	480, 360	Sets the coordinates of the lightposition indicator in the Viewer. The position of this indicator in relation to the center indicator controls the shadow applied to the emboss. NOTE: You can also move the lightposition indicator manually.
Bump Size	bumpsize	1	Sets the size of the emboss applied to the image connected to input B.
Light Height	height	1	Controls the height of the lightposition indicator, where zero is level with the image, producing no emboss. Note: Negative values position the light ’behind’ the image.
Light Intensity	intensity	1	Sets the intensity of the simulated light.
Minimum Shadow Intensity	minshadow	0	Sets the minimum shadow intensity limit. Increasing this value decreases the amount of shadow allowed, and vice versa.
Image Center xy	center	320, 240	Sets the coordinates of the center indicator in the Viewer. The position of the lightposition indicator in relation to this indicator controls the shadow applied to the emboss. NOTE: You can also move the center indicator manually.
mask	N/A	disabled	Enables the associated mask channel to the right. Disabling this checkbox is the same as setting the channel to none.
mask	maskChannelInput	none	The channel to use as a mask. By default, the filter effect is limited to the non-black areas of this channel.
inject	inject	disabled	Copies the mask input to the predefined mask.a channel. Injecting the mask allows you to use the same mask further downstream.
invert	invert_mask	disabled	Inverts the use of the mask channel so that the filter effect is limited to the non-white areas of the mask.
fringe	fringe	disabled	Blurs the edges of the mask.
mix	mix	1	Dissolves between the original image at 0 and the full effect at 1.
