Casting shadows using a directional light, plane, and cast shadow

Question

In the WWDC 2017 video, apple explains about a trick to add shadows by using a directional light. Adding a directional light will cast a shadow and adding a plane will show the shadow. But I cannot seem to find mode and colour options of the cast shadow property. I am not looking to do this programatically. So is there any way there is to change the shadow type to Deferred in Xcode?

Answer 1

If I understand your problem.... Then this image explains what you are trying to do using scen view in Xcode.

You are right, adding plane and directional light with Deferred property will cast shadow. You have to set the x,y and z values of all your scene objects accordingly to show this in a proper way.
