I want to export a certain layer of my work without background as png but it does't work. The exported file has a white background.

I export only the selected area.

I have the new 1.2 version now.

I had no problem with the 1.1.

I found the answer after 1 and a half hour of hard work.

The document page must be set as half color and half empty.

Now it works.

Problem solved. ✅
