Animation parts spread in multiple atlases

Garrett

Hi there ! I work with Spine in Unity, and I encounter a weird problem. The textures used for an animation are spread between multiple atlases, which means that for one animation, there are for example 3 or 4 different atlases (materials) loaded in the MeshRenderer attached to the SkeletonAnimation.

Is it possible to force Spine to export textures used by a same animation grouped in the same atlas ?

Use the Texture Packer without doing Export. You can pack whatever directory full of images you want that way.

Also, if your images don't fit on a single atlas page you can increase the page size. If you want to control which atlas pages images go on, use subdirectories and pack separately from exporting JSON data.

Thanks for your replies, I'll give it a try !

OK I did as you said, and textures are packed within subdirectories.
But when I try to import the skeleton in Unity, I end up with an error saying :
"Error reading skeleton JSON file for SkeletonData asset: skeleton_SkeletonData
Region not found in atlas: [name_of_the_region]"

I had no problem with the previous Export method... Any idea where this could come from ?

Nate

Look at the atlas data file, is the missing region there?

Garrett

You confirm what I just found out ! The missing region is not in the atlas data file.

I removed all occurences to this region from the JSON, and now the skeleton is correctly imported.
I have another problem now, which is totally unrelated, so I'll open a new thread for that one.
Thank you both for your help !
