yugutou Thank you for providing a project that allows us to reproduce the issue! I had suspected that the texture size might be quite large, and sure enough, it was a very large image at 6602 × 3842. It seems improvements are needed to handle tracing operations on very large images.
I’ve achieved quite good results when testing with Spineboy and mix-and-match, so if you’d like to verify the expected behavior, you can try testing those:
