Screen Space Cloud Shadow v1.1.1

Render cloud shadows as a screen-space effect.

- SSCS just renders a Quad.
- SSCS is not a projector.
- SSCS doesn't use ImageEffects.

This is a much faster
and simple to use.
Just drop prefab to your scene.

If your platform supports "_DepthTexture" , SSCS works!
Even works on Mobile!
