Hello,
I tried to modify the black background color. I didn’t find where to change the value. Is it possible ?
Thanks
Vincent
Hi Romeda,
not sure if it’s possible but I think not.
Just export it as PNG.
Tthat means only what’s there is in the file and the rest is transparent.
Then you can add whatever you like in an image processing software of your choice… 
Hello Romeda,
as Gotz has said, it’s not possible in the application. Background color is always transparent black, so if you export it in format that supports alpha transparency (e.g. PNG), you can change the background however you like in other software.
