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.

API:

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
