Hello, I only tested on my win10 computer. I haven't tested other systems. What system is your computer? How to export png images correctly, the first thing to pay attention to is the total number of frames of your animation, and then the total number of frames in the lower timeline should be set. The second point is that the exported image is based on the green square background. The green background squares must be placed one by one. There should be no gap between them. Finally, you can press the number 4 key to export the png image.
