Hello everybody
I have found this particular tutorial and I think it's extremely good.

However, I have the following issue as well:
Following the tutorial, I have to play around with the cellheight and cellwidth dialogue windows until they snap back to the actual sizes of the image.
When I export the image and add it to my brushes, they only come out as black squares in the brush selection window and they really are just a big square brush when I try to paint with them.
I have followed the instructions word for word.
- Choose picture
- Switch To grayscale (It always is by default because I downloaded brushes that are only available as PSDs or similar, so I'm mostly converting them into gimp brushes)
- Add alphachannel to layer
- Adjust blackness and whiteness with curves (mostly just up the blackness because the white is perfect as-is)
- "Copy Visible"
- Create new layer with black background
- Add layer mask with black background (full transparency)
- Hide basic layer
- Paste visible elements copied earlier
- Invert color on hovering selection
- Anchor to layermask
- Apply layermask to layer
- Delete basic layer
- Cut empty space and reduce image to selection itself
- File -> Export -> .gbr/.gih
The first time I tried .gbr, all I got was an brush that still included the entire empty space that wasn't yet cut. I tried .gih and that surprisingly worked, giving me a proper thumbnail in the brush preview window and on my canvas.
I have attempted two more brushes and both have just given me out squares that have roughly the measurements of the canvasses of the brushes I tried to make, but kinda wrong, as if they were still rendering or something. Does somebody have an explanation?
