Creating smoke domain manually instead of using quick smoke makes domain visible When I use quick smoke to create a smoke simulation everything works fine,



but when I create a box and make it a domain, the smoke simulation is not visible in the render due to visible domain?



What's causing this?
That's because the default material for the domain is still enabled 
so you see on that image that it doesn't work
so you have to make a random image and apply quick smoke on it and then delete it and then select the domain again and choose the smoke domain material   and then it works.
