Can directional lights and point lights raytrace shadows simultaneously?

    When my sun gameobject is active, my point lights switch from raytraced to normal. When I set active to false, they switch back to raytraced. Is this supposed to happen, and is there a way to have both work? Or can I only choose one?

    Hey, you need to increase maximum screen space shadow in your current HDRP asset (by default it's set to 4 IIRC).
    Directionnal light raytraced shadows (especially if it's colored) takes 3 of those screen space shadows, area lights 2, and punctual light 1, so when the max number is reached, the shadows fallbacks to rasterization.
