Strip Whitespace does not store amount removed in atlas

isabellel

I have a set of PNG images keyed in Spine. It was originally a mesh animation then exported to a PNG sequence. Now we have to strip whitespace to lower size. So I read the position was supposed to be stored... but when I imported the JSON and atlas back into Spine, the animation is not lined up right. 🙁
Anything I did wrong?

I exported the frames (with whitespace) through JSON export and checked Whitespace stripping. Then imported back to Spine the skeleton and used the Texture Unpacker to bring out the images for the Skeleton's reference.

Hello, you need to check Nonessential data in order for Spine to reimport this in the editor: Export - Spine User Guide

Nonessential data: When checked, additional data is included in the JSON that is not needed to rendering the skeletons. This makes the file slightly larger. This data is needed if the JSON will be imported back into Spine.

Besides, whitespace stripping for meshes is a feature available from Spine 3.7 onwards, but it's not available in 3.6.

Hi Erikari! Thank you! It was very helpful 🙂 We can't use meshes because my team is developing for HTML5 (no mesh, paths, IK inherits, etc 🙁 ). So we have to stick to frame by frame. This helped a lot. Thanks again!

Isabellel, note that while you might not be able to use meshes, you can still use IK, paths, etc. with region attachments!
