Pretty much says it in the title, but when I run a make2d, several new layers are created, as sublayers of the first layer in my list, with nothing in them. They are set to the color white. Strange.
Hi Trygve- I see extra layers as well if I use 'maintain source layers', is that what you are seeing? An extra 'source layer' for each input layer. Looks wrong to me, thanks for pointing it out.
