It would be great to be able to import your own .png textures for example, in addition to a possible base of textures provided.
@Mathieu Michels how?
You can now import custom Note Textures and Sabers into the app in Version 2.0!
You can import just about any image, and .mp4 or .mov videos to use as a Note Texture.
The best website to use for finding images would be Google.com, selecting Images as your search type.
What do I search on to find these and where Do I search?
How do you create note textures? Thanks!
Go to Note Setitngs -> Texture Settings -> Import File and impoert your own texture file
Note: The texture that you download should have two clolors black & white to match with all note colors in the app
wish this is good for you!
