can you please post a sample tiff?
normally, scribus should not have issues with layers in tiffs...
but i cannot create a multilayered tiff from gimp and, since i don't otherwise have a need for tiffs, i cannot really try it out.
this having being said, creating a multilayered psd from gimp and loading it into an image frame does work correctly and the layers are recognized.
can it do it with tiffs, too?
it should...
really, it would be much easier if you just would create a sample tiff (two squares on different layers... that should not be hard to create, if you cannot share the image you have...) and upload it in here.
then we who help have fact to work with and people who will stumble on this thread in the future have things to work with and check if they're doing everything correct.
