zxy it has a effect alpha set to 0,but is still show color.
Could you please describe what you mean by "effect alpha"? What value did you set, and how did you set it in code?
While you could switch to using Tint Black functionality and the respective Spine/Skeleton Tint Black
shader, it's a different approach which requires different setup on the Spine Editor side. However, it's a very powerful feature which allows you to control tint and tint black colors per slot, and allow for animations to control these colors.
