jhuna11003 Did you unpack the images via the Texture Unpacker? If so, apparently you have unpacked a texture with premultiplied alpha without enabling Unpremultiply alpha:

Please try unpacking the texture again with Unpremultiply alpha enabled.

jhuna11003 When you would like to import skeleton data (.json or .skel files), the version in which the data was originally created and the version that you will import into must match, but for unpacking textures, it does not matter if the versions are different, so please use the latest version of Spine to unpack the texture.
