I'm trying to take the belgian and mod it to a solid black coat. First of all, when I extract the .ymt and open it in notepad++, it's all null/encrypted characters. When I open it in OpenIV using its viewer, I can see everything. I can also export it as a .txt or .xml and see everything. Problem is, getting it back to a .ymt file. In the past, I've just used notepad++ and saved as .ymt and it's been fine. I use Lenny's mod loader. Other modded horses are working fine. Now, when I spawn the modded belgian (rampage trainer), my game crashes. If I wait for the game to spawn one on its own, it crashes (just hangs up then closes). When I try to open the edited file in OpenIV, it says error loading file, probable file is corrupt. Then OpenIV has to close saying there's an application error. If I open the file using OpenIV but as a text file, it opens just fine. I had more that I wanted to do to the belgian but I can't even make a single change to the color without this happening. I tried editing a different horse .ymt and the same thing happened. When I go back to the original file and spawn that in, it works fine. I uninstalled and re-installed the game to make sure that's all clean but it's still doing it. I've been looking all over the internet for a program that will convert a file to .ymt to rule out notepad++ but there's nothing. Not for red dead 2. Edit to add: I also re-installed OpenIV and no changes. Any ideas of what to try next?
