This allows you to rotate the selected UV polygons in the UV Editor in 90° increments, either clockwise (90° CW) or counterclockwise (90° CCW).
In addition to the standard UV value range between 0 and 1, any number of UV tiles can also be assigned UV polygons (keyword: UDIM). These buttons allow you to automatically move the selected UV polygons to the next UV tile located above (Up), below (Down), to the Left, or to the Right of the currently selected UV tile.
If you want to move UV polygons directly to a specific UV tile, you can also use Move to tile (see below).
Please note that coordinates can also become negative if UV polygons are moved below the standard tile, for example. However, for the subsequent assignment of textures to individual UV tiles, it is advantageous to use only positive UDIM labels (tiles are all to the right of and/or above the 0..1 standard tile).
UDIM patches have a maximum U index of 10, with virtually unlimited V index.
Here, you can specify a particular tile directly using numerical values. The first value represents the U component of the tile, and the second value represents the V component. After clicking the Move to tile button, the selected polygons are moved directly to the corresponding tile. UDIM patches have a maximum U index of 10, with virtually unlimited V index.
Please note that only positive values can be used here, which results in a shift in UV tiles that lie to the right of or above the 0..1 standard UV tile.
