**Installation Instructions:**
|
|
1. Copy: "https://github.com/JoshuaLim007/Unity-ScreenSpaceReflections-URP.git"
|
|
2. Go into the package manager in unity
|
|
3. Select "add package from git url"
|
|
4. Paste the link into the text entry
|
|
5. Press "add"
|
|
|
|
In your URP Asset

|
|
**Tracing Modes**
|
|
- Linear Tracing
|
|
- Hi-Z Tracing
|
|
|
|
|
|
Hi Z tracing requires "Depth Pyramid" render feature to be added in the pipeline asset. The Depth Pyramid is included in this package.

**Changing settings during runtime**
|
|
|
|
void LimSSR.SetSettings(ScreenSpaceReflectionsSettings o)
|
|
|
|
- `o.StepStrideLength` = The length of each ray march stride. Increasing this will reduce image quality but allow for further objects to be visible in the reflections.
|
|
- `o.MaxSteps` = The number of steps the shader does before ending the ray march. Increasing this will allow further objects to be visible in the reflections but reduce performance.
|
|
- `o.Downsample` = The number of times the working resolution is downscaled. Increasing this will reduce image quality but increase performance.
|
|
- `o.MinSmoothness` = The minimum smoothness of a material has to be in order to have reflections.
|
|
> For the best quality, try to minimize `StepStrideLength` and maximize `MaxSteps`
|
|
|
|
bool LimSSR.Enabled
|
|
|
|
- `True`: Enables effect
|
|
- `False`: Disables effect
|
|
> Enables or disables the SSR shader

static RaytraceModes TracingMode
|
|
|
|
> Sets the tracing mode: Linear tracing, or Hi Z tracing
