SciFiHoloScreen Additive

The SciFiHoloScreen Additive shader renders glowing, transparent sci-fi displays using additive blending. Ideal for HUDs, floating projections, or UI overlays.

Shader Property Description​

Frame​

Controls the outer frame that surrounds the hologram display.

Item	Description
Frame Tint Color (HDR)	Controls the frame color. - Default is white (no change). Adjust HDR color and Intensity to add an emissive effect
Frame Texture	The frame texture. - Use PNG or TGA with an alpha channel so the hologram displays correctly

Hologram​

Controls the hologram content, including color, scale, depth, and the mask texture that defines each layer.

Item	Description
Hologram Tint Color (HDR)	Controls the hologram color. - Default is white (no change). Adjust HDR color and Intensity to add an emissive effect
Use Random Hologram Tint	Sets whether to use a random hologram tint
Random Hologram Tint Blend	Adjusts the blend ratio of the random hologram tint
Random Hologram Tint Intensity	Adjusts the intensity of the random hologram tint
Random Hologram Saturation	Adjusts the saturation of the random hologram
Hologram Mask Texture	The RGBA texture that defines the hologram shape. - Each channel can be combined with the channel properties below for different hologram effects
Hologram Scale	Adjusts the hologram size directly. - Ignored when Hologram Scale Option is MatchObject
Hologram Scale Option	Sets the scaling basis for the hologram. - MatchObject: Scales based on the object size - Independent: Scales independently of the object size
Depth Multiplier	Adjusts the depth of all hologram layers. - Controls the perceived depth of the 3D effect

Red Channel​

Color and depth settings for the red channel layer of the hologram mask texture.

Item	Description
R Channel Color (HDR)	Adjusts the color of the area corresponding to the red channel of the hologram texture
R Channel Depth	Adjusts the depth of the red channel area. - A value of 1 represents a depth of 1 meter from the mesh surface

Green Channel​

Color and depth settings for the green channel layer of the hologram mask texture.

Item	Description
G Channel Color (HDR)	Adjusts the color of the area corresponding to the green channel of the hologram texture
G Channel Depth	Adjusts the depth of the green channel area. - A value of 1 represents a depth of 1 meter from the mesh surface

Blue Channel​

Color and depth settings for the blue channel layer of the hologram mask texture.

Item	Description
B Channel Color (HDR)	Adjusts the color of the area corresponding to the blue channel of the hologram texture
B Channel Depth	Adjusts the depth of the blue channel area. - A value of 1 represents a depth of 1 meter from the mesh surface

Alpha Channel​

Optional fourth layer using the alpha channel. Enable with Use Alpha Channel.

Item	Description
Use Alpha Channel	Enables the alpha channel as an additional hologram layer
Alpha Channel Color (HDR)	Adjusts the color of the alpha channel area
Alpha Channel Depth	Sets the depth of the alpha channel area. - A value of 1 represents a depth of 1 meter from the mesh surface

Backdrop​

Properties that control the background area inside the simulated interior space.

Item	Description
Backdrop Color (HDR)	Sets the background color. - This color is combined with the texture to determine the final color
Use Random Backdrop Color	Sets whether to use a random backdrop color
Random Backdrop Color Intensity	Adjusts the intensity of the random backdrop color
Random Backdrop Color Blend	Adjusts the blend ratio of the random backdrop color
Random Color Swizzle Mode	Sets the random color swizzle mode
Backdrop Color Intensity	Adjusts the brightness of the background color. - Brightness can also be adjusted via the Backdrop Color property, but this is provided as a separate control for convenience
Backdrop Texture	The texture that defines the background. - A grid-type texture that emphasizes the hologram is recommended
Backdrop Scale Option	Sets the scale basis of the background. - MatchObject: The background scales to the object size - Independent: Tiling is maintained regardless of object size
Backdrop Tiling	Controls the tiling of the background texture
Backdrop Depth	Sets the depth of the background space in meters. - A value of 1 sets a depth of 1 meter

Backdrop Fog​

Adds a depth-based gradient inside the backdrop space. Reduces the flat look of the backdrop texture and can simulate light or fog within the interior.

Item	Description
Backdrop Fog Color	Sets the fog color. - Setting a dark color makes the background depth plane stand out less
Backdrop Fog Density	Sets the fog density. - Higher values make the fog thicker and emphasize the light effect behind the hologram
Backdrop Fog Density Remap Min	Sets where the fog begins. - Specified as a percentage of the backdrop depth; for example, if the backdrop depth is 30 meters and this value is 0.1, the fog starts at 3 meters. - The default is 0, starting at the very front of the background
Backdrop Fog Density Remap Max	Sets the point where the fog is thickest. - Also specified as a percentage of the backdrop depth; for example, if the backdrop depth is 30 meters and this value is 0.5, the fog is thickest at 15 meters. - The default is 1, showing maximum density at the far end

SpriteSheet Mode​

Properties available when the hologram mask texture is a sprite sheet.

Item	Description
SpriteSheet Mode	Sets whether to enable SpriteSheet mode
Rows	Sets the number of rows in the sprite sheet
Columns	Sets the number of columns in the sprite sheet
SpriteSheet ID	Sets the SpriteSheet ID to display
Use Random Sprite Sheet ID	Sets whether to use a random SpriteSheet ID

Tips​

• Mix channel colors and depth values for layered hologram effects.
• Backdrop properties add depth behind the hologram layers.
• Backdrop Fog adds depth and atmosphere inside the backdrop space.
