Eurofighter Update to version 1.22 with PBR (Preliminary)


NOTE: THE INITIAL RELEASE OF EUROFIGHTER 1.22 PBR HAD A SMALL GLITCH SO THAT "REMOVE BEFORE FLIGHT" RIBBONS AND COVERS HAD A WRONG TEXTURE - FILES HAVE BEEN REPLACED WITH CORRECTED ONES, ALSO PBR "UBUNTU" MODELS HAVE BEEN ADDED FOR MULTIPLAYER.

A couple of sleepless nights playing with Physically Based Rendering (PBR) on the Eurofighter Typhoon model and here we are with another update. For those who do not know PBR, it is a different rendering technique which is supposed to simulate the appearance of 3D models on the basis actual physical proprieties of the material they represent (such as "metalness", roughness etc.). This is a relatively new rendering technogy which, in some circumstances, can provide more realistic results with respect to the traditional techniques.
Recent videogames like Red Dead Redeption are a great example of this. In flight simulation, PBR was introduced by X-Plane, DCS and (almost unnoticed) by Flight Simulator World.
Note that PBR is a generic name for the approach, and each engine has its own implementation with different results and possibilities.
PBR has recently been introduced in Prepar3D V4 starting from version 4.4 - the implementation is quite standard: materials require an "albedo" texture (its base color), a "metallic" texture (which specifies the metalness and, in P3D, also the Ambient Occlusion and the smoothness of the surface), a "normal" texture (basically the old normal/bump map) and an "emissive" texture.
In addition, P3D now allows the developers to control the visual proprieties of a material with a LUA script during the simulation - which is pretty great as it allows a number of cool tricks.
NOTE THAT PBR MODEL WILL ONLY WORK WITH P3Dv4.4 AND ABOVE.

Here are "preliminary" models of the Eurofighter with PBR. While compiling these models I also fixed a couple of minor bugs. As result the update is provided in 2 versions: a 32-bit version for FSX users and users of P3Dv1, v2 and v3 and a 64-bit version which will only work with P3Dv4.4 (you must upgrade your P3Dv4.X to v4.4 or above to use it).

Here is the list of changes:

VERSION 1.22 WITH PBR UPDATE (BETA)
CHANGES WITH RESPECT TO PREVIOUS VERSION

- Added new PBR models, metallic, bump textures and scripts (Prepar3D v4.4 ONLY!)
- Fixed minor issues and typos in the FCS Autotrim code
- Fixed minor bug in display condition of the ENG FLAME warning in RMHHD
- Fixed miscellaneuos typos in the HUD code
- Fixed miscellaneous typos in the HMD code
- Fixed missing plane attitude graphics in the HMD
- Fixed missing emergency jettison icon
- Fixed missing X FER caption
- Fixed miscellaneous typos in the Tactical Systems code
- Added missing wheels and ground roll sounds
- Fixed glitch in gun funnel mode in 2D HUD view
- Changed HMD code so that A-A symbols will not park at the edge of the FOV
- Fixed minor glitch in panel backlighting
- Fixed multiple minor geometry glitches in virtual cockpit

Hi, questions regarding the EF-2000 ver 1.24. I am unable to engage parking brake with cockpit switch, it clicks but does not move, although I can disengage switch. This is using the virtual cockpit mode, so I'm looking sideways at the panel. Is there another view for just the panels? Have gone over the manual but haven't found anything about panel views. Also the aircraft creeps forward with the brake on and engines running, so after 5 minutes it will move onto a taxiway. I also cannot operate the L & R LP cocks, I can open the red covers, the switch makes a click sound, but cannot shut down engines.

I have the same issues as above.. Whilst the throttles are completely set back, the engines are still running. And parking brake switch doesn’t work, cannot move the gen switches individually and when the frame to switch the switches on, I cannot turn them off individually.
