To enhance character customization, we need to support the creation of Spine attachments using atlasRegion. This feature will allow for dynamic partial character customization by enabling the replacement of specific regions (e.g., clothing, accessories) on the fly without requiring a complete texture swap.

Goals:

• Implement the ability to create attachments using atlasRegion.
• Allow developers to dynamically replace specific parts of a character's texture with custom regions.
• Ensure that the new attachments integrate seamlessly with existing Spine animations.
