NOVA allows to apply real-time environement texture texture, also called Cube Maps, to object in order to reflect the exact surrounding 3D scene.
NOVA also knows howw to extract such textures, in DDS format. The user can freely edit them in Photoshop, often to obtain a realistic staic texture. The process looks like that :
NOVA -> Extraction of the CubeMap->Photoshop->Opening with the DDs plugin -> processing -> saving and closing.
The issue here is a Phtoshop concern, but a little theory makes sense: DirectX9 manages textures in RGBA format (which is very common)where DirectX10 uses ARGB texture format. If you extract a Cube map from a NOVA DX10 scene, the incoming format will be ARGB, in .dds.
Photoshop does still not know how to open dds files (which is actualy the most common format for game industry...). So, you need a plugin to open the file. The best know plugin for Photoshop to open DDS files is the piece of software distributed freely by nVidia (http://www.nvidia.com/object/photoshop_dds_plugins.html). That plugin is pretty out of date and does not know either how to correctly open a directX10 dds format. You will obviously see that some colors are mismatched...

Let's see how to correct that issue.

First open your DDS file with Photoshop. Then go to the Image menu -> Adjustments -> Channel Mixer, and set the properties this way :
For the output Red channel: Red 0%, Green 0%, Blue 100%.
For the output Green channel: Red 0%, green 100%, Blue 0%.
For the output blue channel: Red 100%, Green 0%, Blue 0%.
Close the Channel mixer. Your texture should look good. Save the dds file, using the specific Cube map options.
