Remarks

Functionality for fading in/out texture mip-levels.

Variables

	Name	Description
float	BiasOffset	Difference between total texture mipcount and the starting mipcount for the fade.
float	MipCountDelta	Number of mip-levels to fade (negative if fading out / decreasing the mipcount).
float	MipCountFadingRate	Number of seconds to interpolate through all MipCountDelta (inverted).
float	StartTime	Timestamp when the fade was started.
float	TotalMipCount	Number of mip-levels in the texture.

Constructors

	Name	Description
	FMipBiasFade()	Default constructor that sets all values to default (no mips).

Functions

	Name	Description
float	CalcMipBias()	Calculates the interpolated mip-bias based on the current time.
bool	IsFading()	Checks whether the mip-bias is still interpolating.
void	SetNewMipCount ( float ActualMipCount, float TargetMipCount, double LastRenderTime, EMipFadeSettings FadeSetting )	Sets up a new interpolation target for the mip-bias.
