Atlas problem with flags "strip whitespace X / Y"

Darky

There is a problem when exporting an atlas setting the flags "strip whitespace X / Y", if you use skinned meshes and large images which can be stripped.

The problem seems that the uvs are not well calculated and the texture not looks well, at least using the spine-c runtime.

Note that the problem disappear when you uncheck these flags.

Sorry for my poor english.

This is a well known limitation. When using Meshes you can't use white space stripping when exporting.

This is also mentioned in our user guide

Do you have any plans to correct it?

It's not a bug. "A mesh may have texture coordinates in the whitespace. If the whitespace was removed, the mesh would use pixels outside of the mesh's texture atlas region.

Each image for a mesh should only contain the whitespace the mesh requires and whitespace stripping should be disabled in the texture packer settings."

For meshes you should trim whitespace you don't need before using the image in Spine.

You can recalculate the texture coords or not to trim only the textures that are used in a mesh, or load it correctly in your runtime.
It is not a bug, it is a feature, sound a bit lazy, hehe

It's a lot of work for the packer to know about uvs so it can partially trim mesh regions. It's not so hard to trim the images outside Spine. 🙂
