I will make a new update available in the texture pack.
This update will have some additional settings, which allow you to create borders more precisely.
I will provide a small
tutorial, which will explain how to use this update.
This update will allow you to create advanced border textures without any kind of mirror-mode error.
For those who do not know, the mirroring mode is the texture repetition from right to left.
Depending on the complexity of the texture, this mode may have some flaws, this is due to sizing and positioning errors.
With this update, these errors will be fixed.
The files will be posted next week.
Some examples below.
The borders shown in the screenshots above were created using this new update.
