Hello, I'm currently in the process of making a portrait mod of my own, but I find it limiting when it comes to the size of the actual png, could anyone give me advice on what to do? I'm familiar with the xnb process, but everytime I load in the picture the game crashes (Abigail being the test dummy) Her spritesheet:
I am pretty sure that portraits in the game are hard-coded to be a certain size and ratio. Making them any larger would cause the game to crash because it's not being read properly; you would need a SMAPI mod to be able to make high resoluton portraits (with the same fixed ratio) to get it to work. Luckily there is a mod that does just that: you can try Portraiture and see how that goes.
