This is really a fantastic piece of software, I highly recommend everyone checking it out if you're into pattern/texture map creation.
“For 3D modelers, Filter Forge is a dream come true. It creates seamless textures with a single mouse click. The professional version creates the following map types for any texture: bump, normal, specular strength, specular exponent, diffuse, metallic, and alpha. The same filter can be used to generate any resolution, since filters are procedural.”
Filter Forge is an excellent filter creation tool with a strong community spirit that will enhance your Photoshop creations.”
