Cycletex: Retro Texture Tool

Cycletex has a Free Demo - which is the best way to know what this tool does.

Turn photos into seamless game textures. You will literally learn how to make a seamless texture using this program in 5 minutes tops, & then you'll keep making textures because... I made it fun.

If you're making hundreds of textures for environments in your game, you could probably finish most of them in a night.

The program specializes in creating textures that resemble the "32 bit" era.

Features:

• Polygon select perspective flattening (if the object in the photo isn't flat, it's no biggie)
• Automatic "Make Seamless" which makes seamless texture stitching easy
• Tutorials (missions) which earn you fake money for later planned features (the whole program is a little gamified, but not distracting)
• Color limiting, hue, saturation, brightness, & contrast shifting
• Cropping (by 16 or 8 pixel chunks is optional)
• Easy Downscaling (downscales after you crop automatically)
• Separate preview window
• Modern & Pixel themes with editable colors
• Easy Background Removal (with 2 select-able colors) or automatic foreground selection based on a central object

Screenshots show the program & textures that were created with it.
