In Procreate Dreams you can draw and paint at much larger resolutions and zoom out much further than in Procreate. To achieve these resolutions, the level of detail will change depending on how far you zoom in or out.

When you zoom out and paint, your strokes will be scaled up when you zoom back in, which can cause your strokes to look blurry or pixelated.

If you want to preserve more detail in your strokes, paint as zoomed-in as necessary for your animation's final resolution.
