Unlit

Unlit is the most basic shading model, under which no light source from the engine can affect the final effect, and is applicable to:

• Objects that are not affected by light sources
• Scenes with low screen requirements or high performance requirements

When switching the shader to the Creator's built-in unlit shader (builtin-unlit.effect) in the material's Effect property, the following image is shown:

Art standards

For technical selection, to work with lighting under a model using the unlit material, draw the lighting information on the texture map and then drag the texture map into the MainTexture property box of the material.

To use PBR lighting, see: Physically Based Rendering

Parameters

parameter	description
mainTexture	The main texture
tilingOffset	Scaling and offset of the model UV, xy corresponds to scaling, zw corresponds to offset
mainColor	The main color, which will be processed within the slice shader
colorScale	Multiply with main color to scale the main color
alphaThreshold	Used for semi-transparent tests, with USE_ALPHA_TEST enabled, pixels smaller than this value will be discarded

Pre-compiled macro definitions

macro	description
USE_INSTANCING	Whether to enable GPU geometry instancing
USE_VERTEX_COLOR	Whether to overlay vertex colors and alpha values
USE_TEXTURE	Whether to use the main texture (mainTexture)
USE_ALPHA_TEST	Whether to perform translucency testing (AlphaTest)
SAMPLE_FROM_RT	Whether to sample from the RenderTexture or not, when checked the Y value of the UV will be flipped
