Hello, Just updating AB4D to the latest version from v7.1 and it looks like it has broken some of my code for doing an offscreen render then saving to a bitmap.

Calling RendToBitmap on a DXViewportView used to work. But now it's just a blank image. Rendering the camera still works, but is very slow.

Any ideas on a fix?

Best regards,

Simon

Code snippet below

Code:

  var viewport3D = new Viewport3D();
            var directxViewPort = new DXViewportView();
            directxViewPort.InitializeScene();

            directxViewPort.BeginInit();

            directxViewPort.Viewport3D = viewport3D;
            directxViewPort.Height = 2048;
            directxViewPort.Width = 2048;

            viewport3D.Width = 2048;
            viewport3D.Height = 2048;

            var camera = new FirstPersonCamera();
            camera.Position = new Point3D(0, 0, 0);
            camera.Bank = 0;
            camera.Heading = 0;
            camera.Attitude = -90;
            camera.FieldOfView = 92;
            camera.TargetViewport3D = viewport3D;

            foreach (var m in objs.Values)
            {
                viewport3D.Children.Add(m.CreateModelVisual3D());
            }

            camera.Refresh();


            directxViewPort.EndInit();

            var img2 = directxViewPort.RenderToBitmap(2048, 2048, -1, 96, 96);  //this line used to work, but now the image is just blank

            var img = camera.RenderToBitmap(backgroundBrush);  //this works but is very very slow
