Hi Wyatt,
When I have one or two objects, say the size of a car, or truck, only. The
shadow map looks correct. But when I add my terrain which is approximately x
= 5100 by y = 5100, I no longer see the car/truck shadows on the shadow map.
Similarly, if I increase the length and width of the

Hi Wyatt,
I have changed to a LISPSM shadow technique.

Hi Wojtek,
Generally yes, But don't turn them off but rather alter them with your
modified shaders.

When you use scale in a Transform, the geometry's normals also get
scaled. The normals are used to compute lighting, so it's normal

You just need to tell OpenGL to rescale normals:

Why do I have multiple SceneViews?
