Hit point is not visible, the DepthRaycastHit.point contains the last visible point on ray.

Call EnvironmentDepthManagerRaycastExtensions.SetRaycastWarmUpEnabled with 'true' to keep the depth raycast always ready.

Depth raycast only works with the visible area in front of the user.

Raycast ray is completely occluded by the depth texture.

Either no depth info is available yet or the raycast's maxDistance is less than the environment depth.

The intersection with the environment is found. EnvironmentRaycastManager.Raycast returns 'true' only in this case.

The ray intersects with the environment, but the actual hit point is invisible.

The raycasting system is not ready yet or the EnvironmentRaycastManager is not enabled. It takes several frames after the EnvironmentRaycastManager is enabled before the raycast is ready.

The hit point can't be determined because it lies outside of the depth camera frustum.

The ray is completely occluded by the environment.

The intersection with the environment is not found.

The environment raycast is not supported. Check the EnvironmentRaycastManager.IsSupported before calling raycasting methods.
