Ray-traced Directional Light shadows with colored shadows Note: When you use a Directional Light with a transmissive GameObject, HDRP displays rasterized shadows on the reverse side of the GameObject. Ray-traced shadows allow for transparent and transmissive GameObjects, lit by Directional Lights, to cast colored shadows. Ray-traced Directional Light shadows (Sun Angle = 0.53, the angle of the Sun as seen from Earth) Ray-traced Directional Light shadows (Sun Angle = 0) Ray-traced shadows offer an alternative to the cascade shadow map that Directional Lights use for opaque GameObjects. To change the behavior of the shadows, edit the properties under Ray-Traced Shadows.

For Directional Lights, you need to enable Screen Space Shadows to access this property. Also in the Shadow Map foldout, enable Ray-Traced Shadows.Under the Shadow Map fold-out in the Shadows section, click the Enable checkbox.Select Camera from the Default Frame Settings For drop-down.įinally, to make HDRP process ray-traced shadows for your Directional, Point, or Rectangle Light:.Open the Project Settings window (menu: Edit > Project Settings), then select the HDRP Default Settings tab.Then make sure you enable Screen Space Shadows for your Cameras. If there are more than this number of Lights in your Scene then HDRP only ray casts the shadows for this number of them, then uses a shadow map for the rest. Set the value for Maximum to be the maximum number of screen space shadows you want to evaluate each frame.In the Lighting section, enable Screen Space Shadows.Click on your HDRP Asset in the Project window to view it in the Inspector.To use ray-traced shadows, enable screen space shadows in your HDRP Project. This means that HDRP stores them in a screen space buffer which holds the information for every pixel on the screen that is in the depth buffer (which only stores opaque GameObjects). Using ray-traced shadowsĪll ray-traced shadows are screen space shadows. When you enable ray-traced shadows in your HDRP Project, they replace shadow maps for opaque GameObjects. Ray-traced shadows are shadows that HDRP generates by tracing rays of light from the following Light sources:
