When you go to settings where you can change the backgrounds color you can change the visibility of the background and make it the same color as the sides but sadly when you like play your animation the background becomes black and not transparent I don’t understand this it seems like an easy fix. And this problem makes it really hard to make assets like for object shows since there’s no transparency.
It may not be able to render transparency
you are right
it seems that the css for body and canvas background-color get bypassed by some code
event settings them as !important wont let you do it
It would be useful to be able to set whatever body background and also have canvas transparent !
you may edit this post and convert it in bug or feature request type.
