How to set an object to NOT recieve shadows?

I have objects in my scene that are receiving shadows when I do not want them to. Below is a water plane with receive shadows disabled. But it’s not working. I suppose that is only for Mobile (that’s what it says anyways). Is there another way?

I don’t think you can set an object not to receive shadow, but you can set one not to cast. You could do that with the runway there…

Yup that’s what I had to do. Thanks.

Whats up with all the jaggies?
