UDK

When adding new functionality to this you will sadly need to touch a number of places:

MaterialInstanceTimeVarying.uc  for the actual data that will be used in the game
MaterialEditorInstanceTimeVarying.uc for the editor property dialog that will be used to edit the data you just added

void UMaterialEditorInstanceTimeVarying::CopyToSourceInstance()
   template< typename MI_TYPE, typename ARRAY_TYPE >    (this copies
   void UpdateParameterValueOverTimeValues(

void UMaterialEditorInstanceTimeVarying::RegenerateArrays()

the various void UMaterialInstanceTimeVarying::Set   (to set the defaul values)

static void UpdateMICResources(UMaterialInstanceTimeVarying* Instance)   (to send the data over to the rendering thread (if it needs it)

[edit] FontParameterValueOverTime

Extends: ParameterValueOverTime

Modifiers: native

Font FontValue 

int FontPage 

[edit] ParameterValueOverTime

Modifiers: native

Object.Guid ExpressionGUID 

float StartTime 

when this is parameter is to start "ticking" then this value will be set to the current game time *

name ParameterName 

bool bLoop 

if true, then the CycleTime is the loop time and time loops *

bool bAutoActivate 

This will auto activate this param *

float CycleTime 

this controls time normalization and the loop time *

bool bNormalizeTime 

if true, then the CycleTime is used to scale time so all keys are between zero and one *

Default values:

[edit] ScalarParameterValueOverTime

Extends: ParameterValueOverTime

Modifiers: native

float ParameterValue 

This allows MITVs to have both single scalar and curve values *

Object.InterpCurveFloat ParameterValueCurve 

This will automatically be used if there are any values in this Curve *

Extends: ParameterValueOverTime

Modifiers: native

Texture ParameterValue 

[edit] VectorParameterValueOverTime

Extends: ParameterValueOverTime

Modifiers: native

Object.LinearColor ParameterValue 

Object.InterpCurveVector ParameterValueCurve 

This will automatically be used if there are any values in this Curve *

[edit] Native functions

[edit] ClearParameterValues

Overrides: MaterialInstance.ClearParameterValues

Removes all parameter values

[edit] SetFontParameterValue

Overrides: MaterialInstance.SetFontParameterValue

Sets the value of the given font parameter.

Parameters:

• ParameterName - The name of the font parameter
• OutFontValue - New font value to set for this MIC
• OutFontPage - New font page value to set for this MIC

[edit] SetParent

Overrides: MaterialInstance.SetParent

[edit] SetScalarCurveParameterValue

Overrides: MaterialInstance.SetScalarCurveParameterValue

[edit] SetScalarParameterValue

Overrides: MaterialInstance.SetScalarParameterValue

For MITVs you can utilize both single Scalar values and InterpCurve values.

If there is any data in the InterpCurve, then the MITV will utilize that. Else it will utilize the Scalar value of the same name.

[edit] SetScalarStartTime

This sets how long after the MITV has been spawned to start "ticking" the named Scalar InterpCurve *

[edit] SetTextureParameterValue

Overrides: MaterialInstance.SetTextureParameterValue

[edit] SetVectorCurveParameterValue

[edit] SetVectorParameterValue

Overrides: MaterialInstance.SetVectorParameterValue

[edit] SetVectorStartTime

This sets how long after the MITV has been spawned to start "ticking" the named Scalar InterpCurve *
