Compatibility
Is Envtex compatible with weather engines ?
Envtex is fully compatible with any weather engine like ASP4, AS16, ASN or OpusFSI but you won't be able to use the ASCA integration feature if you don't use the ASP4 / AS16 + ASCA combo.
Is Envshade compatible with Reshade ?
Yes, Envshade is fully compatible with Reshade, however we do not recommend to use it not to alter the realistic rendering of Envshade.
Is Envshade compatible with PTA and Tomatoshade ?
Yes... and no, depending on the settings applied in PTA, both products can interfer and completely destroy your simulator shaders. While this can be simply reverted by the Envdir restore function, we recommend not to use PTA at the same time as Envshade.
Do I need Envtex to use Envshade ?
No, Envshade can be used as a standalone product, but the best results will be reached using Envtex and Envshade all together.
How to use Envtex with a weather engine from Hifi Simulation ?
Nothing specific is required to use Envtex with AS16, ASP4 or ASN.
If you want to use Envtex clouds with ASCA, you must enable the corresponding cloud (Cirrus or Cumulus) in Envtex and disable the corresponding clouds (Cirrus or clouds) in ASCA.
In ASCA integration setting, you must use "Envtex sky textures only" if you want ASCA to use only Envtex sky textures. If you want ASCA to use both Envtex and ASCA sky textures, then use "ASCA + Envtex sky textures"
Are your product compatible with my other addons ?
All our products are fully compatible with any other 3rd party addons, including all weather engines (i.e. Hifi AS16, ASP4, ASN, ASE, ASCA, REX4, REX Skyforce), all orbx products or any 3rd party sceneries.
For your comfort and ease of use, our products are customizable, you can disable any feature you don't want to be installed in case it would interfer with another product.
Do you need some guidance to make Envtex working with Hifi or REX weather engine? Please refer to "How to use Envtex with weather engines" below.
How to use Envtex with a weather engine from REX simulation ?
Envtex can be used with any REX weather engine, we highly recommend to turn off the textures you don't want to use from REX in the corresponding user interface.
Activation
My product is not correctly activated in Envdir, what should I do ?
Product shows as "Not activated" in Envdir
If you do not see such a pop-up windows, your product was probably not properly installed and some files or registry entries are missing. Please try reinstalling the corresponding product again with administrator rights.
I used all my activations, how can I reset the activations count ?
If this happens, we recommend to contact directly simmarket through their ticket system explaining what happened: secure.simmarket.com/ticket_create.php

Issues
Envdir installation hangs
Please make sure you are running Envtex with admin rights. To do so right click on Envtex then “Properties”, take a look in the compatibility tab and check the box “Always run as an administrator”, apply and leave this window. Envtex should then install correctly the files to your simulator.
If this does not work please also check if your simulator folder is not set as a hidden folder, as well as your suneffect.cfg file (located in "C:\ProgramData\LockheedMartin\Prepar3d vx\" for P3D).
Envdir launch sim button triggers an error message
Please first check your simulator path is set correctly. If so, please make sure you are running Envtex with admin rights (see previous section).
Envdir installation is very long
Envtex moves a huge amount of data during the install process, if you are using a slow hard drive disk or if you PC specs are low then installation can take a few minutes.
This should not happen on usual or high end computers.
Envtex makes my sun disappear
Please make sure you are running Envtex with admin rights. To do so right click on Envtex then “Properties”, take a look in the compatibility tab and check the box “Always run as an administrator”, apply and leave this window. Envtex should then install correctly the files to your simulator.
If this does not work please also check if your simulator folder is not set as a hidden folder, as well as your suneffect.cfg file (located in "C:\ProgramData\LockheedMartin\Prepar3d vx\" for P3D).
Envtex Aurora - Northern/Southern lights are not visible
These are a P3D exclusive feature and require some specific settings as described in the Special effects chapter. They mostly appear during winter and only at high latitudes. We highly recommend to generate a new flight instead of loading a saved flight situation as the special effects may not be loading correctly by Prepar3D.
Please check your Prepar3D settings are set to the minimum requirements:
Please feel free to contact us in case of any trouble.
Envdir crashes to desktop
Envdir needs .NET framework 4.5.2. If it is not installed on your system, you have normally been redirected to the official download link during the installation process. If it failed or if you removed it, Envtex may not be able to work. In case this happens, we recommend to check that .NET framework is still installed. If this is not the case, we invite you to download .NET framework from the official Microsoft website: www.microsoft.com/en-US/download/details.aspx?id=42642
- Programs & Features
- Turn Windows features on or off (top left on the page)
- In the new panel : expand : ".NET Framework 4.7 Advanced Services"
- Ensure that : ASP.NET 4.7 is ticked
If you still get a crash to desktop, please feel free to contact us by mail or by using our support forum.
Envshade makes the ground or clouds disappearing
This means an incompatible version of shaders have been installed into your simulator, probably an older version of envshade into the latest version of Prepar3D.
Envdir does not save my settings
This usually happens when you have been using an older version of Envdir. One of the early version had a bug which was corrupting the user settings.
The only way to solve this is to reset the settings once by clicking "Reset Envdir settings" from the windows start menu. If it does not work, please try again by right clicking and select "Run as an administrator".
As the newer versions of Envdir do not have this issue anymore, the issue should not appear again.
Envupdater is already used by another process
Some users met an issue when trying to update Envdir and Env products. After clicking the update button, this message may appear:
If this does not help, please feel free to contact us, we will help you as quickly as possible.
My screen becomes completely white when using Envshade on P3Dv5
The current version of P3Dv5 still have an issue with the bloom effect not working properly. For most users this does not create any issue other than the bloom not working as expected but for a few users, it creates a huge surexposure that makes the screen being completely white.
If you meet this issue, please make sure to do one of these :
- Decrease bloom to 0 (You will not lose anything as the bloom is not working properly at normal values)
Repaints
Do you accept repaint requests ?
Unfortunately, due to the amount of work involved in our recent products, we do not have the resources anymore to actively create aircraft repaints. We will keep create repaints from time to time but we do not accept requests anymore.
