Can't load a map

[0scar123456789]

I just made a greyscale height and RGB texture map. Yet, when I go to the FH game, map maker, It is not there. What am I doing wrong? Both Height and texture maps are saved as a PNG file.

Here is where they are both saved as:
(C:)>FeralHeart>media>terrains>TheGathering
(The Gathering is a folder I created, was not sure if I had to make a file of just leave both in the terrains folder)

Here are the titles of the maps

thegatheringMask.png (This is the RGB texture map)
thegatheringterrain.png (This is the greyscale height map)

This was all done in GIMP if that makes a difference.
Please help!
Thank you

First make sure your heightmap is:
- Grayscale
- One layer
- No Alpha Channel
- .png image
- 513x513

Now, also delete that folder but keep the mask and terrain of course. Put them straight into the terrains folder.

And what should happen is that when you enter Map Maker, go to the "World" tab and enter them into the sections where they're supposed to go. Then that should make it appear on the Map. c:

Make sure the image size is 513x513 also
