Misaki Sorry, could you please detail the solution you provided? I do not know what to even modify in the .json file, but I'm not sure if it's practical to use it if I need to change the destination folder for different exports.
In my case, I want to control the naming behavior according to the needs of a game developing group. Some PNGs need to be in a named sub-folder, so the PNG file names only need to be numbers. My clients may demand different number of digits (0, 00, 000, 0000).
I definitely think it's beneficial to have more Export customization in the Editor, such as being able to create a new subfolder based on specific names, like the animation name. Also, the dashes (-) are not good for game programming.
