== Weighted Blend Node ==

The Weighted Blend node outputs the result of an average sum of each one of its [[#paramLayer|Layer]] values multiplied by their respective [[#paramWeights|Weights]]. The amount of available layers is determined by the amount of channels given by the connection data type on the weights input.
<br/>P.e. a Vector4 is connected to the Weights Input, input ports Layer 1 through 4 will be made available and the resulting value will be ''( Weights.x*Layer1 + Weights.y*Layer2 +Weights.z*Layer3 +Weights.w*Layer4 )/ (Weights.x + Weights.y + Weights.z + Weights.w )''.
<br/>If Layers are of different types and have different channel amounts then a cast is done for each to match the one with the most amount of channels.

'''NOTE:''' Other types of blending are also available via the [[Unity_Products:Amplify_Shader_Editor/Summed_Blend|Summed Blend]] and [[Unity_Products:Amplify_Shader_Editor/Layered_Blend|Layered Blend]] nodes.
