Hi, @刘少发. Thanks so much for your post, and apologies for replying in English - I don’t speak Chinese.
When you say that sliced and exported images fail to display correctly, what do you mean? Are they failing to export at all, or do they export but not look correct? If it’s the latter, attaching the slice exports and the full export here so I can see the difference would be helpful. One other thing you can try: if you’re using the desktop app, switch to a web browser or vice versa.
