I'm not very knowledgeable about this, but it would be cool to see a filter in this program that turns regular textures into normal map textures, as well as a couple more algorithms for texture seamlessness. For example, I saw an algorithm that makes images hexagonal, but again, I don't know much about that. I also have an idea for a new mechanic: for example, I have two photos, a photo of a wall and a photo of a hole. It would be cool if I could overlay the hole texture as a new layer or something similar on the already processed wall texture. This can be done in other editors, but it would be really cool if your program supported this!

Wow, I've already downloaded it, thank you so much for not abandoning the project!

I never saw this sorry! I'm not sure how I would implement a metallic map generator besides using the brightness of the pixels and coloring them into a metallic map. You can already kind of do this by making it black and white and then using the color limiter to make it 2 colors.
