Prepar3D v3.4 Now Available

As one of the most well-respected flight simulators out there, P3D has long been one of the most exciting to use. However, it’s a simulator that regularly gets updated and improve to further satisfy user demand. The latest release for P3D, version 3.4, is here. This latest update brings a gluttony of new changes to the table. It also introduces some exciting new features from rendering changes to new SDK management tools.

If you like to use P3D then you should have no problem using the new update. It further improves what is already an exemplary simulator.

Prepar3D v3.4 Update

What’s New?

In this mod, you can finally expect to have access for Oculus Rift 1.7 and HTC Vive. This is BIG. It’s a major part of the virtual world to have VR access and this will only seek to further the experience for everyone. It also introduces fresh new navigation visuals to the UI. This includes new work on facilities, airspace, user and AI overlays into the 3D world.

Scaleform gauges are now included which support multi-touch usage. Alongside this, we get Avatar support for weaponry. Now you can fire and aim guns – this is a long-term aim for the simulator so it’s a big improvement.

Also, we’re getting access to new Cinematographer control modes. This enables high fidelity camera controls which go the distance. With new control events to help rotate cameras without irritating snapping back and centring, too, you should find it easier to fly at your own orientation.

Best of all, new control inputs are included. Now you can switch between Raw and Direct input systems. But that isn’t all this new update brings to the table. It makes massive changes and fixes, rendering improvements, SimDirector changes, multiplayer additions, DIS and SDK updates and more.

Brilliant New Bug Fixes

This is the perfect solution for anyone who wishes to enjoy a much more refined P3D experience. For example, this improves issues where gauges would be prevented from handling successive mouse clicks.

Your ATC panel has been changed to always be on top of other panels, also. With mission time panels now supporting negative numbers, also, these adjustments are worth having. Many small issues are adjusted, such as;

  • Expanded .fxml documentation in the Learning Centre.
  • Scenery items added now prevent negative layer ordering.
  • Provides key commands to the ADF standby frequency.
  • New maximum zoom levels.
  • Far more robust system for handling errors with better detail.
  • Fixed numerous crashes, such as docked views being clicked causing crashes.
  • Scenery which has been added using an add-on will default on the top layer.
  • Controller triggers can now be used to fire guns.
  • Scaleform panels now don’t pass key events to the main application.
  • Stronger general control support for everything from throttle and rudder management to camera adjustment and selecting views.
  • Drag-to-select has been improved for multiple weather stations being modified via global weather settings.
  • Issues revolving the avatar rendering when using HIdeUserAvatar was set in the camera. Incorrect items can also no longer be activated when using the keyboard now.
  • X-Grip input issue are improved and removed from the scene.
  • Fixed the big in both Fuel and Payload UI systems whereby centre of gravity would be displayed in the wrong location.
  • Fixed numerous typos and mistakes on most screens.
  • Remove various start-up crashes if ShadersHLSL path was invalid.
  • Child views within view groups are now capable of being closed.
  • ATC windows no longer process key inputs when the menu is focused.
  • Bug fixes also prevent vehicles from receiving mouse yoke values when using mouse look.
  • And much more!

Rendering Improvements

Another major factor of this mod has been the introduction of the new rendering and performance features. For one, screenshots can now be saved outside in various formats such as JPEG/PNG/BMP/TIFF.

Also, added support for network video streaming is included, alongside support for alpha blending when using custom zbias rendering.

Adjustments to the overall fixes and performance include;

  • Fixed the major issues whereby changing texture resolutions wouldn’t cause reloading to occur.
  • Removed bugs that caused add-on scenery to appear to look dull during certain times.
  • Fixed precision errors when using certain LLA conversions.
  • Fixed visual and performance-based problems with aircraft skid marks.
  • Fixed bugs with bloom properties not carrying themselves accordingly.
  • Also sorted problems with beacon sprites not rendering accordingly.
  • Likewise, the axis indicator has been made red to make it easier viewed at all times.
  • Better stability when using ultra water has been included, too.
  • Added OpenCL support to the ultra water to make sure it works better on AMD cards.

SimDirector Changes

Making use of the Virtual Instructor system has just been made easier, for one. This introduces camera objects and user virtual cockpits which can be previewed when editing. Also, this has seen the introduction of PlacementObject, SetObjectPlacementAction and ChangeObjectPlacementAction. Each action provides an excellent new feature for easier reposition, alignment and orientation of objects for advanced waypoint following etc.

Also, new additions include the introduction of Activate/Deactivate all selected objects using the Context menu.

Fire off actions when objects reach certain waypoints, or finished within a waypoint listing provided.

New mappable objects have been included to position and re-position various objects.

Added a new ability to set Prepar3Ds default scenario to your edited scenario.

Also, this introduces various new improvements also;

I've purchased P3D and am having trouble getting it to load...keep getting an error - when I try to sign-on with a query, one of the questions asked is: "what are the 5 middle characters (OUT OF 11) in the following sequence"? How do you acquire 5 middle characters out of 11 that make no sense?
