Texture Correction Tools
In general, automatic texture correction is not an easy task, especially when the problem is, "We can only export one texture, even though there are two." In many cases, if visual accuracy is important to your export, you will have to perform the correction manually, assisted by the Texture Validation Tools. The Virtualwind Plugin does offer one automatic texture correction tool, which takes care of many visual inaccuracies as well as geometric inaccuracies. This is the Flip Back-Only Textured Faces Tool.
Flip Back-Only Textured Faces

Recall from the section on "texture theory" that faces with a texture only on the "back" side are usually "incorrectly" pointing inward. There is nothing inherently incorrect about an inward-pointing front face. It is only "incorrect" in the context of Virtualwind's assumptions on Canopy geometry.
The "Flip Back-Only Textured Faces" tool exploits that heuristic. It identifies all Faces that have been textured only on the back side. It then reports back to you with how many such Faces it found, and asks if you want to flip them. If you select "Yes", the tool will automatically reverse the orientation of these Faces, and it will move the texture from the back side to the front side. When this is complete, it will then ask if you wish to display only the affected Faces. If you select "Yes" again, it will show all affected Faces and hide everything else – the original visible state of the geometry is then lost.
In case high fidelity visual accuracy is necessary, it is worth noting that the "flip" operation is not strictly image-preserving. In particular, the resulting positioning is a mirror of the original positioning. Although this can have a dramatic effect in principle, texture images are often such that the effect is hardly noticeable in practice.
This tool searches all geometry within the model, ignoring the visibility settings it encounters. To access this tool, click its icon in the toolbar, or from the main menu, select the Plugins → Virtualwind → Correction tools → Flip back-only Textured Faces sub-menu item.
