Virtual Flight and Weather Engine: REX (Real Environment XTreme)

REX

REX offers two important elements through its different products: 1) A weather engine that downloads real weather in your computer while replicating the different weather phenomenon, through its REX Essential Plus program and 2) very realistic cloud textures (through its add-ons like Overdrive, Texture Direct, Soft Clouds).

A flight planning mode is also included, as well as numerous options to create specific weather themes that take care of the appearance of the clouds, the quality of the light in the sky, the definition of the sun effects, the different textures and colors of water.

You also have the possibility to choose different runway markings, the sounds associated with thunderstorms and the type of lightning that will illuminate your virtual sky.

REX is compatible with all platforms, including X-Plane.

Here are the REX products, which each play a very different role:

REX Essential Plus: a weather engine and a product that contains cloud textures and multiple options in order to simulate as much as possible the real outside weather for the area you have chosen. The weather engine will soon be renewed with a new addition: REX Weather Direct.

REX Overdrive: adds 12 GB of cloud textures.

REX4 Texture Direct: adds another 16 GB of cloud textures, and a possibility to create complete weather themes according to your preferences, while you still have access to other themes created by all the virtual pilots of the REX community.

REX Soft Clouds: adds volumetric clouds in the lower layer of the atmosphere for a more realistic effect.

REX4 Weather Architect: a program that allows you to create a precise weather system then position it anywhere on the planet. This is not a weather engine: It will not look for new data on internet and download it in your computer.

REX Weather Direct: a soon to be released improved weather engine that will be compatible with DX9, DX10 and DX11 as well as with FSX, FSX: SE (Steam Edition) and P3D.

On virtual flying forums, users seem to have a preference for the Active Sky Next (ASN) weather engine combined with REX cloud textures. This is a good combination, but it’s not the only one that deserves attention: FSGRW together with REX cloud textures do an excellent job (this is the duo that I am using for very precise results). There is also OpusFSI with REX, ASN with ASN2012 (ASN weather engine combined with ASN2012 cloud textures) or even a REX only set of programs (soon to be available REX Weather Direct and REX cloud textures).

This all depends on your priority: the FSGRW simplicity and absolute realism, the facility to use a cockpit camera and the dynamic head movements supported mode of OpusFSI, etc. It is best to read a lot and take the necessary time before jumping to quickly to a conclusion.

Some weather engines might need tweaking or modifications to be compatible with the most recent versions of P3D, if we believe what is written on specialized forums.

Virtual Flight and Weather Engine: OpusFSI

It used to be called OpusFSX, but that was before P3D arrived on the market. Now it is OpusFSI (a more generic name applicable to many platforms)

OpusFSI

OpusFSI is a weather engine which, like FSGRWASN or REX, downloads real live weather close to your route and integrates it in your computer so that your virtual flight is always done in actualized weather. All those programs will update the data more frequently if the weather deteriorates along your flight path.

OpusFSI does not add new cloud texture sets. If you wish to fly in more interesting clouds, you need to use OpusFSI in combination with REX.

Opus works well on a network, which is practical if you want to transfer some OpusFSI functions towards a second computer to limit the use of the main computer’s resources.

OpusFSI is compatible with FSX, FSX: SE and P3D and even with TrackIR real-time 3D view controls (some files will have to be deactivated in the Program Files if you were using TrackIR before buying Opus). You have access to multiple interactive maps to check the weather or SIDs/Stars and to adjust the many options according to your taste.

OpusFSI is quite an advanced program that is well adapted to the use of virtual cockpit cameras. It replicates head movements caused by vibrations or turbulence and allows views from left to right when taxiing or turning in flight. The effects are all adjustable by the user.

If you are using many computer screens for your virtual flight, you can program each screen to show a different view (like the left and right window, for example).

OpusFSI allows you to use historical weather. The program also offers the possibility to relocate the weather over an airport towards another one. As well, you can decide to make some low clouds disappear or eliminate any obstruction to visibility when you want to have a perfect view of the territory. You can even create your own Metar.

Like for other weather engines on the market, you have access to a “flight planning mode”.

An option allows you to include turbulence and wind shear caused by the surrounding terrain within 80 kilometers of an airport.

The data generated by OpusFSI can be used directly in the PMDG B737NGX. That means you can see the real weather on the aircraft’s radar.

OpusFSI is in continual development and new functions are frequently added. They are not all mentioned in the present article.

Like for other weather engines available on the market, it is necessary for you to visit the company’s web site in order to choose the most appropriate software that will be adapted to your type of virtual flying and to the equipment that you use or intend to use in the future.
