When you have to drag up the pattern for the animation, make sure it starts and ends with the same image, use the flattened version as a guide to know where to put it. I know this comment is hella old but it might help someone out!
I managed to do this but I'm having trouble merging it with a gif. I have an already animated frame animation of lava but when I try to add the embers it loses it's animation. How do I fix this?
