Shadow Rendering: shadows only render above a certain distance from the Entities

[consansri]

Hey :D

It seems like my shadows are only rendering when the Camera has a certain distance from the Entities.

Camera near entities:

Camera far from entities:

It seems like they are rendering just above a certain horizon:

is that intentional? Or you have any idea how to fix that?

I checked your source-code twice so it should be similar if i didn't miss anything :)

Just one quick question. Does the example from the book out of the box works for you?

same issue here

Can you please share the exact camera coordinates that provoke this issue? I'm not able to reproduce it.

[consansri]

Camera Position where it starts to render the shadows on the left upper corner.

radius: somewhere from 15 to 20

Seems like it depends not only on the position but also on the rotation when looking from above the rendered shadows change also when only the camera rotation is changed.

Sorry but I'm still not able to reproduce it. Please do as follows:

• Use the source code of chapter-21.
• In the init method of the Main class, set up the position and rotation values that trigger the issue. Now it looks like this:

        Camera camera = scene.getCamera();
        camera.setPosition(-1.5f, 3.0f, 4.5f);
        camera.addRotation((float) Math.toRadians(15.0f), (float) Math.toRadians(390.f));

• Post that fragment here so I can check on my side.

The shadows of the blocks slightly start to render. At this position:

Camera camera = scene.getCamera();        
camera.setPosition(-4.5f, 3.0f, 14.5f);
camera.addRotation((float) Math.toRadians(15.0f), (float) Math.toRadians(390.f));

Hi,

Still unable to rpeoduce the issue. With those parameters I see shadows rendered perfectly. Let's try some new things:

• Can you debug the shadow cascades (displaying the cascades as in previous samples) to check if theer is something wrong there?
• Can you check with render doc what is being rendered in the shadow buffers for each cascade?
