Currently, Spine does not support defining detailed bone parameters such as length, rotation, and position directly within PSD layer tags. The existing tags like [bone] and [origin] are used to create bones and set their origins, but more detailed configuration must be done within the Spine editor itself.
However, there are plans to enhance the PSD import functionality. For example, the [origin] tag is being considered to mark bone origins without exporting the layer as a PNG. This would help in placing images accurately in Photoshop, but detailed bone parameters still need to be adjusted in Spine.
For now, you can use the existing tags to set up the basic bone structure and then fine-tune the parameters within the Spine editor.
