caochangli Based on my testing with Spineboy in Spine 4.3-beta, packing via the CLI correctly referenced the mesh polygons. However, the results were different when packing the texture in the editor versus packing it via the CLI. I suspect this discrepancy is causing the polygons to appear unreferenced. For reference, my test results are as follows:
Packing via the Spine Editor GUI:

Packing via CLI:

The difference may be difficult to see, but in both the upper and lower results, you can see that the other images are positioned right on the edges of the gun and board. This is the result of referencing polygons. If the parameter -j
for specifying the project is omitted, the following results will be obtained:

Without seeing the actual files, we can only speculate why you cannot obtain the desired pack result. Please send the files to us via email so we can check what the problem is. Please send them to us via email so we can check what the problem is: contact@esotericsoftware.com.
