- Performance
- Hierarchical Z-depth casting
- Temporal reflection depth reprojection
- Median Filtering for extra denoising
- Reflection Color Mipmap Pyramid
- Raycast and resolve pass downsampling
- Frame reprojection for faking multiple bounces
- Specular elongation
- Contact hardening
- Works only with deferred rendering
- Compute shader capable video card
- Unity Post Processing v2
- Tested with Unity 2018.2
In a unity project go to your Packages folder. Open manifest.json and add into the dependencies the following line:
"com.simeonradivoev.stochastic-reflections": "https://github.com/simeonradivoev/ComputeStochasticReflections.git"
It should look something like this:
{
"dependencies": {
"com.unity.ugui": "1.0.0",
"com.unity.modules.ui": "1.0.0",
"com.simeonradivoev.stochastic-reflections": "https://github.com/simeonradivoev/ComputeStochasticReflections.git",
}
}
Just add a new effect in a post processing profile under Custom/Stochastic Screen Space Reflections
For VR use the test branch called StereoRendering. It currently only supports multi pass rendering.
