Emissive Material

metal_base.remt

You can make engine\materials\metal_base.remt glow by adding the correct parameters, or you can poke through the game files and search for emissive > .mi to find Cyberpunk material templates to learn from.

For a list of such templates, check here.

PARAMETER	DESCRIPTION
Emissive	path to emissive texture, e.g. engine\textures\editor\white.xbm The texture works like an alpha mask.
EmissiveEV	float, e.g. 2.0: emissive brightness. Brightness varies depending on your colour. Unless you want to actively blind people, you might want to stay below 4.
EmissiveColor	Glow colour as RGB (copy from e.g. mi_neokitsch_fridge_z_emissive.mi)

Find a ready-to-use glowing .mi file here.

device_diode.mt

You can find the shader under base/fx/shaders/device_diode.mt

The properties need to be documented at some point

---

screen_fluff_{color}.mi / parallaxscreen.mt

There are several versions, located at base\materials\screen\

Screen fluff is the effect used on items with a digital/led decoration like pozer jackets, infovisors, and ocusets. It's also used for a lot of monitors and screens.

All materials using the parallaxscreen.mt baseMaterial share the same parameters.

PARAMETER	DESCRIPTION
ParalaxTexture	The image that will be displayed on the screen.
LayersSeparation	Determines the depth of the Paralax effect. Higher the number, deeper the effect.
ScanlineTexture	Texture of the Scanlines effect. (especially visible when paired with a blinking mask)
ScanlinesDensity	Determines the amount/thickness of the scanlines.
Emissive	The brightness of the display.
EmissiveColor	Determines the color of the Emissive.
ScrollMaskTexture	GREEN (scroll1) and RED (scroll2) on black mask. Determines how a scrolling animation is applied to the ParalaxTexture.
ScrollSpeed1	Determines the speed of the scrolling animation of the GREEN masked area.
ScrollSpeed2	Determines the speed of the scrolling animation of the RED masked area.
ScrollVerticalOrHorizontal	Determines if the scrolling of the masked area will be Vertical (0) or Horizontal (1).
BlinkingMaskTexture	Black and white mask. Determines which area of the ParalaxTexture will "blink" (white area will be static, black area will blink)
BlinkingSpeed	Determines the speed of the blinking of the BLACK masked area.
HSV_Mod	See below.

There are additional properties that haven't been documented yet.

HSV_Mod

Modifies the colour of the screen/glow.

PARAMETER	DESCRIPTION
X	Hue. A degree from 0° to 360° in a colour wheel where 0° is red, 120° is green, and 240° is blue, represented as a decimal between 0 and 1. See examples below.
Y	Saturation. A value between 0 and 1, with 1 being fully saturated and 0 being unsaturated.
Z	Unknown. Doesn't seem to have an effect.
W	Unknown. Doesn't seem to have an effect.

Examples

Colour	Position	Percentage	X
Red	0°	0% (0/360)	0.000
Yellow	60°	16.66% (60/360)	0.1666
Cyan	180°	50% (180/360)	0.5000

Results appear to be the same regardless of which version of screen_fluff is used, but the colour of the ParalaxTexture does matter. This can lead to unpredictable results if a coloured ParalaxTexture is used. The blend mode (the method used to determine how the colours are combined) applied appears to be divide. Results will be more predictable if a black and white ParalaxTexture is used.
