Which specific aspect of the built-in solution is not working for you? Any examples?
Things to note:
- margins are percentages
- in
Border
mode use the smallest image dimensions you’ll ever need and only scale up - not all images can be 9-sliced
- when working with materials, don’t forget to set
Image Size
(256x256) below - it will affect how the material behaves
The margin of .1 is enough in this example, as 10% of the edge is just enough to exclude from scaling.
It will always break at very small sizes as there’s not enough pixels to work with.
