Hello there.
I was Wondering about what if we could Generate Textures in some sort of Plugin Pack, Like in this Program Called Texture Maker.

For One, we could Generate Scratch Noise and Rectangles, to have some Nice Base Metals for Other Metal Related Textures.

But Also, we could have Features from Wally in this Plugin Pack, Like a Scratch Tool, Bullet Hole Tool, and Even a Rivet Tool, so Rivets, Bolts, and Corrugation can be Placed on your Textures.

Hopefully, someone can do these Ideas, and Share it with the Paint.net Texture Designing World!
