public void setReceivesShadows(boolean receivesShadows) {
        this.receivesShadows = receivesShadows;
    }
Set if the material should receive shadows or not.

<p>This value is merely a marker, by itself it does nothing.
Generally model loaders will use this marker to indicate
the material should receive shadows and therefore any
geometries using it should have {@link com.jme3.renderer.queue.RenderQueue.ShadowMode#Receive} set
on them.

@param receivesShadows if the material should receive shadows or not.
