Tiler is an incredibly useful plugin for Adobe Photoshop that allows 3D artists to make seamless textures. Tiler works by wrapping and fading off each side of the image onto the opposite one.
Tiler provides controls for adjusting the side of the wrap for both the horizontal and vertical edges independently.
Additionally, the user can shift the newly-tiled image horizontally or vertically or quickly preview the new horizontal and vertical seams with the toggle of a button.
Tiler provides locks for uniform horizontal and vertical wrapping.
Tiler supports both 8 bits / channel and 16 bits / channel color modes for professional workflows.
