Shadow Receiver HDRP (Directional & Additional Light Shadows)

Shadow Receiver uses a custom shader to render real-time shadows onto any 3D object. The shadows can be cast from any real-time light in Unity!

Made for the High Definition Render Pipeline (HDRP).

Universal Render Pipeline (URP) version here.

📱 Augmented Reality/Mixed Reality

Shadow Receiver is mostly used in AR/MR to render shadows on planes detected with plane detection. This way, an AR object can have realistic real-time shadows in AR. This creates a more immersive AR experience.

Of course, feel free to use this for any other project you see fit!

🎥 Video Compositing/Virtual Production

Shadow Receiver can be used well with video compositing in Unity. As long as your video uses alpha clipping to be able to cast shadows, you can get real-time shadows below it.
