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!

# Spherize Node
|
|
|
|
## Description
|
|
|
|
Applies a spherical warping effect similar to a fisheye camera lens to the value of input **UV**. The center reference point of the warping effect is defined by input **Center** and the overall strength of the effect is defined by the value of input **Strength**. Input **Offset** can be used to offset the individual channels of the result.

## Generated Code Example
|
|
|
|
The following example code represents one possible outcome of this node.
|
|
|
|
```
|
|
void Unity_Spherize_float(float2 UV, float2 Center, float Strength, float2 Offset, out float2 Out)
|
|
{
|
|
float2 delta = UV - Center;
|
|
float delta2 = dot(delta.xy, delta.xy);
|
|
float delta4 = delta2 * delta2;
|
|
float2 delta_offset = delta4 * Strength;
|
|
Out = UV + delta * delta_offset + Offset;
|
|
}
|
|
```
