Examples

How to perform standard rendering:

class StandardRenderingExample
{
    public void Render()
    {
        // Copy default settings
        var settings = CameraRenderSettings.Default;
        // Adapt default settings to our custom usage
        settings.position.position = new Vector3(0, 1, 0);
        settings.camera.frustum.fieldOfView = 60.0f;
        // Get our render target
        var rt = new RenderTexture(128, 128, 1, GraphicsFormat.B8G8R8A8_SNorm);
        HDRenderUtilities.Render(settings, rt);
        // Do something with rt
        rt.Release();
    }
}

How to perform a cubemap rendering:

class CubemapRenderExample
{
    public void Render()
    {
        // Copy default settings
        var settings = CameraRenderSettings.Default;
        // Adapt default settings to our custom usage
        settings.position.position = new Vector3(0, 1, 0);
        settings.camera.physical.iso = 800.0f;
        // Frustum settings are ignored and driven by the cubemap rendering
        // Get our render target
        var rt = new RenderTexture(128, 128, 1, GraphicsFormat.B8G8R8A8_SNorm)
        {
            dimension = TextureDimension.Cube
        };
        // The TextureDimension is detected and the renderer will perform a cubemap rendering.
        HDRenderUtilities.Render(settings, rt);
        // Do something with rt
        rt.Release();
    }
}
