Smoke Domain renders as a grayish box I know that this question has been asked, but unfortunally there was no answer- maybe through a second try someone else will read this and can help.

Im pretty new to blender, so sorry for my messed up blender file.





as you can see, the smoke domain of my cycles quick smoke effect is being rendered as a semi-transparent-box.
i turned off the shadows in the cycle settings of the domain and the smoke object, so this is not the problem.

-> .blend


really looking forward for some help,
greets,

Sorry this is not an answer. 

I will delete, just so I can post a pic. 

I just opened your file, disconnected all the image textures (because they were not packed) 

Then I just hit Render with all your settings and it doesnt have that same error that yours does. 

This is what I got. 



Maybe someone else can try your file and see if they can replicate it. It seems like a hardware glitch. Change to a GPU (if you can) see if that changes anything.
