# Naming animation files

Image filenames to be used in your animations must follow the following pattern: X_YY.png, where X stands for the animation name and YY stands for the frame number.

Key points:

- The Animation part will ignore any files that do not match this pattern in your selected directory.
- The animation name must be separated from the frame number by an underscore (_).
- Spaces or special characters, such as "& ( ) #", are not allowed. If you want spaces to appear in the animation name, you can use underscores (e.g., Open_door_001.png). The underscores will be removed when the files are loaded into the Animation part.
- In addition to .png files, the Animation part will also recognise: .bmp, .xpm, .jpg, and .jpeg.
