Alpha Channel for Background object in c4d


HI. Is there any way i could apply alpha channel to background object? I basically have a scene where i imported my green screen plate (png image), which has an alpha channel in it. But when i drop in onto background object, alpha channel does’t work, its all black. Even though when i apply that material to plane or whatever 3d oject it works fine. What should i do? Because i still need that image which has correct aspect ration, etc to lineup my scene properly.


You cannot use it in background object but you can use it in foreground object
