export images without shadows?
Hello! I have some troubles epxporting images. 
The layer structure is the following:
group1
|_ group2
     |_ bitmap layer
     |_ mask
The masked bitmap layer contains **no** shadows, but 'group1' has a shadow. I'm trying to export only the bitmap layer(and also group2), but the exported image contains the shadow of 'group1' also.

Is there ant way to export only the image without any shadow? I want to mention that I found the same behaviour when exporting from the tool. It looks like a bug, I'm not sure.
Any help would be really appreciated!
