Version 2.4 Build 63 will be released shortly. It has the following highlights.
Generation 4/5 Shadows
Improved Shadow Accuracy. Figure 2 is V2.3, Figure 3 is V2.4 Note Antennae shadow and shadow at rear of wing.
Look at shadow under wing leading edge in Figures 4 and 5 and 6 and 7 (Odd figures are new version)
In the VC the shadows line up much better with the window frame Figure 9 is new version.
Improvements to HD Shadows
In previous releases HD Shadows worked well with any aircraft for which the Virtual Cockpit Model just modelled the cockpit without the wings.
This was usually the case for airliners with swept back wings which cannot easily be seen (if at all) from the cockpit.
There were therefore two downsides
If the HD shadow option was enabled and the VC model then contained wings or other external aircraft parts then the behaviour was very
poor – strange false shadows would sweep across the cockpit when panning the viewpoint around.
Shadows were disabled for external cameras within the aircraft radius (i.e closer than the spot view) – but this matching was not 100% and so
for a few aircraft some surfaces within the VC would not show shadows and/or external close cameras would show false shadows.
In this release the implementation now operates like a cookie cutter centered at the camera and discards portsions of the model that might cause issues when HD shadowing is enabled.
This means that HD shadowing can be successfully used acrosss a much wider range of aircraft without false shadows.
The following pictures show the improvement that HD Shadows can give with a plane of DC3 dimensions – Baslar BT67 (Daniel Fuernkaess, Manfred Jahn, Alexander M. Metzger, Hansjoerg Naegele).
Unshadowed Surfaces Fix
A few aircraft had surfaces which didn’t show shadows when HD shadows was selected. Here is an example.
With the new behaviour it has been possible to provide an option to extend HD shadows for smaller aircraft.
The gain with very small aircraft is not so dramatic as with larger aircraft and may not be worth the compromises in external cameras. For example the high winged Cessnas suffer an issue
with the wing supporting struts which appear to be unshaded as they get further from the plane.
