I updated everything to the latest Unity Editor. Also realized I had the wrong shaders on my hairs, those are fixed and the hairs look MUCH better!

# Matrix Construction Node
|
|
|
|
## Description
|
|
|
|
Constructs square matrices from the four input vectors **M0**, **M1**, **M2** and **M3**. This node can be used to generate matrices of types **Matrix 2x2**, **Matrix 3x3** and **Matrix 4x4**.
|
|
|
|
The dropdown on the node can be used to select whether the inputs values specify the matrix rows or columns.
|
|
|
|
* **Row** : Input vectors specify matrix rows from top to bottom.
|
|
* **Column** : Input vectors specify matrix columns from left to right.
|
|
|
|
Matrix outputs are taken from the top left corner of the construction of the inputs. This can be used to generate different dimension square matrices from different dimension vectors.
|
|
|
|
For example, connecting **Vector 2** type values to inputs **M0** and **M1** will generate the desired matrix from the output **2x2**.

|
The following example code represents one possible outcome of this node per mode.
|
|
|
|
**Row**
|
|
|
|
```
|
|
void Unity_MatrixConstruction_Row_float(float4 M0, float4 M1, float4 M2, float3 M3, out float4x4 Out4x4, out float3x3 Out3x3, out float2x2 Out2x2)
|
|
{
|
|
Out4x4 = float4x4(M0.x, M0.y, M0.z, M0.w, M1.x, M1.y, M1.z, M1.w, M2.x, M2.y, M2.z, M2.w, M3.x, M3.y, M3.z, M3.w);
|
|
Out3x3 = float3x3(M0.x, M0.y, M0.z, M1.x, M1.y, M1.z, M2.x, M2.y, M2.z);
|
|
Out2x2 = float2x2(M0.x, M0.y, M1.x, M1.y);
|
|
}
|
|
```
|
|
|
|
**Column**
|
|
|
|
```
|
|
void Unity_MatrixConstruction_Column_float(float4 M0, float4 M1, float4 M2, float3 M3, out float4x4 Out4x4, out float3x3 Out3x3, out float2x2 Out2x2)
|
|
{
|
|
Out4x4 = float4x4(M0.x, M1.x, M2.x, M3.x, M0.y, M1.y, M2.y, M3.y, M0.z, M1.z, M2.z, M3.z, M0.w, M1.w, M2.w, M3.w);
|
|
Out3x3 = float3x3(M0.x, M1.x, M2.x, M0.y, M1.y, M2.y, M0.z, M1.z, M2.z);
|
|
Out2x2 = float2x2(M0.x, M1.x, M0.y, M1.y);
