# UDIM/UVTILE file identification

UDIM/UVTILE files are recognized as such (e.g. by the **Open Texture** command) if the file names of image sequences contain the following characters:

- four-digit numbers beginning with the digit 1, e.g. **xxx_1001**, **xxx_1002**, the numbers indicate the tiles according to the illustration [here](https://help.maxon.net/c4d/en-us/Content/html/Udim.html.md). The token in file paths for this is **\<UDIM>**.
- _u##_v## , where "##" are numbers, e.g. **_u0_v0_xxx**, **_u0_v1_xxx**, where the numbers indicate the tile coordinates in the UV direction. The token in file paths for this is **\<uvtile>** (lower case).
- there are programs that by definition use _u1_v1 as the first tile at the bottom left, in this case **\<UVTILE>** (capitalized) must be used as the token in file paths.

See also the illustration [here](https://help.maxon.net/c4d/en-us/Content/html/Udim.html.md) for the tile designation and coordinates.
