Species Unknown

Overview

U+ for Species Unknown is a graphics enhancement and performance improvement mod that provides advanced control over lighting, reflections, and visual effects.

Setting	Options	Keybind	Description
BetterReflectionSDFs	game,off,on		Increases the resolution of meshes in global software lumen space, most noticeable in reflections
Bloom	game/0-3	CTRL+F3	Bloom intensity (0.0 = off, 1.0 = default, 2.0 = double, game = use game default)
DynamicFPS	game/0-240		Target FPS for dynamic adjustment (0 = off, 30-240 = target framerate) - press ALT + F12 to disable dynamic FPS and save current settings
EnableKeybinds	off,on		Enables individual setting keybinds if they are available, does not change global keybinds
ExtendedFogQuality	game,epic,ultra,insane		extended volumetric fog quality settings
ExtendedShadowQuality	game,veryhigh,epic,insane		extended shadow quality for both regular and virtual shadows
Fog	game,off,on,on_with_lumen		Turns fog on or off, if on_with_lumen is provided then it allows enabling fog in lumen space (GI and reflections)
LODBias	game,off,minuspoint5,minus1,minus1point5,minus2		Forces textures to be higher resolution, -0.5 is the safest, more can cause frequency patterns to appear, some games benefit from more than others
LODDistanceScale	game,high,veryhigh,epic,ultra,insane		Draw static meshes and foliage at higher quality further away
LensFlare	game,off,on		Allows disabling lens flare
LightDrawDistance	game,x1_0,x1_5,x2_0,x2_5,x3_0		light draw distance scale
LightingAO	lumen,lumen_less_noise,ssao,gtao	F7	Changes ambient occlusion method between Lumen, SSAO, or GTAO - lumen_less_noise is the safest default as full lumen may introduce shimmering/noise
LightingMode	game,standard,advanced	F8	lighting mode - standard for default enhanced lighting, advanced for higher quality - game will disable and revert all lighting changes
LightingQuality	game,standard,high,veryhigh,epic,insane	CTRL+F10	Standard lighting quality is the recommended default, higher lighting qualities will reduce noise and increase the detail of lighting in the scene particularly around smaller object
LightingResolution	low,medium,mediumhigh,high,veryhigh,epic,insane,extreme	F6	lighting resolution quality - higher quality is more accurate lighting at the cost of performance - standard in-game epic (the same as epic in this setting) is typically x16 downsampling which is usually not necessary, medium (x32) is the minimum recommended
LightingUpdateSpeed	default,high,epic,insane		Allows making global illumination update faster
LumenTraceDistance	game/20000-60000		Maximum distance of objects traced in the lumen scene
MotionBlur	game/0-1		U+ improves motion blur quality in every game by default, recommend a small amount of blur ~0.2
ReduceInputLatency	game,off,on		reduce input latency at potential FPS cost if not GPU bound
ReflectionBias	game/0-1	F9	Adds smoothing to reflections to make them more mirror like, a small amount is usually beneficial
ReflectionQuality	game,high,veryhigh,epic,insane	F10	Allows more surfaces to be included in reflections, in some games increasing this can cause some noise
Sharpness	game/0-1		Control UE tonemapper sharpness - recommend setting this to 0 and using RCAS through reshade
SkylightIntensity	game/0-3		Skylight is a flat amount of light added to the scene, it mostly effects outdoors unless a game uses it to light interiors
SkylightLeaking	game/0-1	CTRL+F2	How much of the skylight is allowed to leak into indoors or occluded areas
ViewDistanceScale	game,one,two,three,four		increases view distance scale, affects foliage most noticeably
Vignette	game,off,on	F3	vignette effect control
VirtualShadows	game,off,on		Enables UE5 virtual shadow maps which are higher quality
VolumetricFog	game,off,on,on_disable_emissive	F5	Turns volumetric fog on or off, if on_disable_emissive is provided - it disables the emissive component of fog which can cause fog to be overly intense and washed out
