Hi,
I created different frames for a gif animation. It is the same picture (polymer chain) but some small molecules moving around. I added the frame but when I run the animation, instead of saying the polymer molecule fixed and the small molecules moving, I saw all the picture moving. I did resizing and put all the same size but it did not work. How can I fix the size of the frames so that it appears fixed with the only small molecules rotating? Thank you for your help and your prompt response.
