Check and fix the normal format for some voxel textures that are currently Direct X.
In working on a tutorial, I realized that the EarthStone_ng file and the Far versions for this voxel texture are in Direct X format rather than OpenGL. I know this isn't the case for all of the textures, but I don't know how many more have this issue. Each voxel texture should be checked and fixed.
Put the normal for the file in a program like Substance Designer as an image (which is what I was doing when I found out).
Make sure the default normal format for the program is OpenGL.
Use a Convert To Height process on the image.
Convert the height back to an OpenGL normal.
If the original normal is OpenGL, the result of this process should be a similar image.
If the result isn't similar, then the original is a Direct X normal.
