Spawn Entity using procedurally generated texture?

[Liam19]

I have a 2D terrain system that loads in chunks as images (basically like minecraft chunks and render distance). In this case, chunks are just an image that is generated at runtime based on a seed.

The issue is that i can't see any other way of spawning these chunks other than saving the image to disk, then loading them back in. This is because spawning a SpriteBundle requires an image handle rather than the actual image.
But the images will be so large and numerous that it becomes impractical to keep it all on disk.

Is there a way to spawn the chunk into the world without loading the image from disk?

After generating the Image you should be able to directly add it to the assets collection

fn generate_images(mut images: ResMut<Assets<Image>>) {
    let image: Image = ..generate your image;
    let handle = images.add(image);
    // save the handle or directly use it
}

This does not save the image on disc.
