plunksville I understand your situation, but I am afraid that we cannot answer exactly when. Also, there is a possibility that this issue cannot be resolved due to a problem on the functional side of Photoshop. I’m sorry for the inconvenience, but please see if the studio can enable
Strip whitespace X/Y for the Spine project. It is enabled by default in 4.0, so unless the studio has it disabled, it should be enabled.
