Feral Heart

So i wanted to try again doing a map (the last time it didn't wroked and i gave up)

(I used Paint Tool Sai)
So i did the terrain like that and i named it BorkTerrain.png

And the mask (i named it BorkMask.png)

I saved them in FeralHeart>>Media>>Terrains, when i opened the map maker and i writed the terrain name in the World selection it didn't crashed the game but when i clicked to change the mask name it, it crashed

 So i helped my bff installing fh but when she opens it doesn't work, it appears "FeralHeart,exe has stopped working".

So i decided to try this year to do animations for fh but because is the new version and the problem with the old animations i don't know what another program i need, i have already blender

 So i've seen a preset with only markings and i wanted to try but i don't know how to do this in gimp, is a guide for this?

I wanted to make a scrolling preset but in game in preset maker I can't see preset_3Lhead, i have this code
