I've discovered that working with artists on a videogame is the equivalent of the chapter when Homer asks for a wish to a monkey arm on the Simpsons.

- I want a png image of the player on idle position. And I dont want a 30000 x 30000 image, neither an image which half of it are transparent pixels, neither the image not to be centered or any strange thing ok?

*They send the image*

- Normal resolution, well drawn, no visual artifacts centered on the image...

*Tries to import it on the game engine*

+ Can't import .jpg format images

- FFFFFFFF#@€&£$$}•{^÷|CK!

This happened after a year working on the same project on the same engine with the same image format specifications.
