Let me give my question the background.
I think about drawing my own character animations. It seems that I would do that in a file, for example in krita or photoshop (suggestions welcome).
If you look at the software shoebox (https://renderhjs.net/shoebox/), you have the option to extract sprites and create texture atlas from split images.
May I say that the workflow would be like this:
- Draw my character animations in a transparent image file
- Split it into separate sprites with Shoebox
- Mount it with Shoebox to a textured atlas
Thanks for the answers!
