If there is a free normal map generator that works for you that’s great!
I personally couldn’t find one that worked for me and that is why I created this app.
It wasn’t until down the line that I thought hey if I needed this then maybe there are other people that could benefit from it too :)
PixelNormalGen is specifically for people who want that nice edge-lighting fx on their pixel art sprites which is something that I had a hard time trying to find on the market.
