== Weighted Blend Node ==
== World To Object Matrix 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.
The World To Object Matrix node outputs the current inverse model matrix which can be used to transform either a position or direction vector from world space to object/local space.
<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.
'''NOTE:''' We advise using either the [[Unity_Products:Amplify_Shader_Editor/Transform_Position|Transform Position]] or [[Unity_Products:Amplify_Shader_Editor/Transform_Direction|Transform Direction]] as they are easier to use and you wont need to do an explicit multiplication between matrix and position/direction value.

World To Object Matrix Node

The World To Object Matrix node outputs the current inverse model matrix which can be used to transform either a position or direction vector from world space to object/local space.

NOTE: We advise using either the Transform Position or Transform Direction as they are easier to use and you wont need to do an explicit multiplication between matrix and position/direction value.

Output Port Description Type
Out Returns current inverse model matrix value. Matrix4x4
