[Covering a branch with a texture]

Add a new layer. Put the texture in the new layer, flatten and erase the red

[Animated Image 2.4 - AGIF & APNG]

I am also having trouble with transparent backgrounds though?

I open 4 .png files in layers, I hit save as, and save the file as 1.agif

then I rename and just take out the "a" from .agif but the background

is black? Do I have to change something in each layer?

Try making the background white. It worked for me.
