# Unity dynamic light isn't casting shadows

I am using the Lightweight Scriptable Render Pipeline 1.1.11-preview and I have two lights in the scene. One is a Sun light and another is an uplight. The Sun light is set to cast dynamic shadows, as are the particle effect clouds and the models. I am expecting the clouds and the cloudship (the floating thing in the middle of the picture) to cast shadows.

The sand is procedurally generated: a flat prefab is loaded at run time and the y points are set by Perlinn noise. I recalculate the normals using Unity's method.

Here is the scene:

The properties of the Sun light:

The prefab for the sand (which I am expecting to have shadows):

Here is the lighting properties.

The setting window for the Lightweight Pipeline:

The settings for the mesh that should be casting the shadow:

Is there anything I'm missing? Thanks in advance.
