Component:VolumeUnlitMaterial

CollapseComponent image 

Volume Unlit Material component as seen in the Scene Inspector

The VolumeUnlitMaterial component is used to display 3d textures like Xrays, sunbeams, MRIs, CT scans, or any other 3d texture in a volumetric 3d cube that can optionally be sliced. Can also be used for volumetric lighting, but high texture resolutions can be large and cause considerable render lag.

Fields

Fields Collapse

Name	Type	Description
persistent	Bool	Determines whether or not this item will be saved to the server.
UpdateOrder	Int	Controls the order in which this component is updated.
Enabled	Bool	Controls whether or not this component is enabled. Some components stop their functionality when this field is disabled, but some don't.
HighPriorityIntegration	Bool	If true, integrating this asset (e.g. processing procedural assets) gets higher priority than assets with this flag off. An example is user laser procedural meshes.
_shader	Shader	Internal.
Mode	DisplayMode	How to display the texture in 3D space.
BlendMode	BlendMode	How to blend this material's colors vs what it rendered on top of.
RenderQueue	Int	changes at which point a material renders on the render stack
Volume	Texture3D	The 3D texture this material should display.
StepSize	Float	How many cell details there should be.
Gain	Float	How much to gain up the color.
Exp	Float	What exponent to raise colors to.
AccumulationCutoff	Float	if color goes beyond this brightness, don't render it.
HitThreshold	Float
InputRange	Float	What range duration within 0<->1 do the colors in the 3d image have? Useful for isolating particular ranges for densities in a CT scan.
InputOffset	Float	at what point does the range start?
UseAlphaChannel	Bool	Whether to use the alpha channel in the pixel data of Volume.
Slices	list of SlicePlane	Slice planes that cut the volume along local positions and directions.
Highlights	list of Highlight	A list of Highlights to use.
