I have made a border that alpha fades to 0 in the center. The pdn file looks alright but when i export it as 32bit png the alpha fade stops at, i guess, somewhere between 100 to 50 and at which point it cuts off completely. I will upload the png file. If you open it in Paint.net you will see a (rough) transition to 0. But with Unity or windows photo app you can see that it doesn't fade all the way to 0.
Am I doing something wrong or is this a limitation about the PDN software?
