Construct a new shader.

Parameters:

in_shaders - A shader interface

in_shader_env - A shader preprocessing environment

in_pool - The ID pool

Returns:

A new shader

shaderParametersType

public Class<R2LightProjectiveWithShadowVarianceType> shaderParametersType()

Specified by:

shaderParametersType in interface R2ShaderUsableType<R2LightProjectiveWithShadowVarianceType>

Returns:

The shader parameter type

onValidate

public void onValidate()

Specified by:

onValidate in interface R2ShaderUsableType<R2LightProjectiveWithShadowVarianceType>

Throws:

R2ExceptionShaderValidationFailed - If validation fails

onReceiveBoundGeometryBufferTextures
