transparent background image export

I was wondering if it is possible to export an image with a transparent background in Toon Boom?
I tried png export with transparent box checked, but I’m not sure how to get this to work if it is possible.

You can export an image with alpha channel as .png, .psd and .tga
Go to File/Export/Images
Export images dialog box open
Browse destination for saving the file
Set the file type (.png, .psd or .tga)
Colour mode: colour with transparency
Selected frames: the frame to export

Hope that helps.

thats exactly what I did with png.
And does having a layer with a bg affect beneath or not affect the image from having a transparent bg?

I imagine it is exporting the whole scene not just the exported layer.

Hide all the layers except the ones you want to export.
