Hello, I'm currently working on some small project with pixi but with more complex shapes. Now I wanted to look at the image data of my sprites but the pixel values are all 0. I searched on google and a few suggestions were that the renderer hasn't rendered anything yet or that the sprites weren't loaded, but this is not the case because if I take another sprite (the cat from https://github.com/kittykatattack/learningPixi) my program suddenly works (I get an array with more than just all 0)
