To address the blurriness of your Spine character when applying Depth of Field in Unity, you might need to adjust a few settings. First, ensure that the Depth Alpha Cutoff is set to a very low value, such as 0.0001, to avoid cutting off too much of the character's transparency, which can lead to blurriness. Additionally, you can try modifying the render queue of your shader to ensure that the Depth of Field effect is applied correctly. You might also want to check the Advanced - Z Spacing setting to ensure it is not causing Z-fighting or other rendering issues. If these adjustments do not resolve the issue, consider using a different Depth of Field implementation or modifying the order in which the effect is applied in the render queue.
