wpw1221 Hmmm, that sounds strange. If you are following the method presented in that thread, I think you should be able to pack the textures in the same arrangement even if you check the StripwhitespaceX/Y checkbox. Did you use the texture packer to pack both albedo and normal maps? If either is packed at the same time as the JSON or binary export, the results may be different.
If you have both packed with the texture packer, but the results are different, this may be a bug, and we would appreciate it if you could email us the image files that can reproduce the problem: contact@esotericsoftware.com
(You can paint the images a random color or something so we can't see the specific images).
Additionally, I have a minor question: if I place normal maps and albedo maps in the same folder, is it possible to export them separately based on file names or other identifiers? This would be more convenient for file management. However, this issue is not as important as the one above.
It is impossible to separate packs if they are in the exact same folder. If the parent folder is the same and they are each in their own subdirectory, the texture packer will pack them as separate pages unless the Combine subdirectories checkbox is checked in the texture packer settings.
For example, the folder hierarchy should look like this:
<images folder>
├── <albedo>
│ ├── body.png
│ ├── head.png
│ └── ...
└── <normal>
├── body.png
├── head.png
└── ...
In this way, two texture atlas pages can be obtained with a single texture packing.
