....thanks Guy's !
Just to be clear, what is being demonstrated is not able to be applied to FSW default airfields / airports, hence the subject title FSW - ( PBR ) Custom Wet Surface's.
The Custom made Runway and Taxiways featured, are made as FSW Specification Ground Polygons and allow the use of PBR materials to be applied to them. If you would like me to go more into the specifics of this then please let me know.
I haven't yet looked to see if the effect can be ' triggered ' ( Visibility Conditions Coded by the Sim ) by precipitation being present at the User Airfield, in my previous version of the effect for FSX, this was handled by the fabulous SODE utility ( Sim Object Display Engine by Jeffrey Stahli )
......one thing worth mentioning, is that in the Screenshots, the previously created surface materials for FSX, ie the Concrete Taxiway and Asphalt Runway Textures, are not PBR Materials. It is envisaged that if those Surface materials were indeed FSW specification PBR materials, the overall look of the ' Wet Surface Effect ' should be out of this world. ( I may find the time to try it and show you what I mean LOL !!! )
Great screenshots. It would be great if you could explain in details.
So, to give you some idea of the workflow to achieve the ' Wet Surface Effects ' being demonstrated here, take a look below -
You will need an Albedo texture ( Diffuse Colour ) with an Alpha Channel saved in DDS DXT5 format. An Asphalt Texture works well for this purpose.
You will also need to have created a PBR Combined Texture. Use the Albedo Texture to create the required texture maps for this purpose. Follow the FSW SDK instructions here -
As there are many ways in which you can create a Combined Texture Map, as it depends on what Art Authoring Package you have, I will not go into too much detail on this.
For example, I use Substance Designer to Create the ' Combined Texture ' and it is done within a few mouse clicks.
When Created, save the 'Combined Texture ' texture map in TGA format.
Process it using the tools available here in the SDK - Use FSW DDS (DXT1c)
You will then need a ' Bump ' texture map or Normal map to be precise. This is NOT created from the original Albedo texture, but a suitable ' Water ' Bump Map Texture for this purpose.
The way in which this texture is created is exactly the same as per for FSX.
