(
    UMaterialInstance * SourceA,
    UMaterialInstance * SourceB,
    float Alpha
)

Remarks

Interpolates the scalar and vector parameters of this material instance based on two other material instances, and an alpha blending factor The output is the object itself (this). Supports the case SourceA==this || SourceB==this Both material have to be from the same base material

Parameters

Parameter	Description
SourceA	value that is used for Alpha=0, silently ignores the case if 0
SourceB	value that is used for Alpha=1, silently ignores the case if 0
