I am so sorry I just can't find anywhere else to ask.
There was no doggytalents folder under assets so I made one myself, along with the following folders in the path. I named the one I'm experimenting with 'doggytex28' and it isn't showing up in game. I have no idea what I'm doing, this is my first time with this sort of thing.

I've tried other names too, including doggytex$NUM$ exactly. I've tried it with an actual number, I've even tried adding .png to the end of the name (I full knew that would not work)
What am I supposed to be doing here?

I also apologize for the lack of labels, I think the layout changed and the location to add labels (i.e bug, etc) is not immediately obvious to me.

First off, don't worry, cause you are in the right place to ask, feel free.
Yeah, it is my bad that i havent got the chance to document the massive texture changes in DTN 1.11.0. Apparently the old naming convention is not used anymore, so there is no "doggytex$NUM$" type file. The changes is to allows dogs to have different models accross skins. Currently there is two ways to add the texture in, the easier way is to edit the mod's jar file assest itself. There is a skin.json file that you have to edit to register your skins in.

Ah, thank you! I have no clue how to do that but I'm sure I'll figure it out at some point
