pre keyed footage and blender

hey guys

how do you use pre keyed footage with blender please? can i use import images as planes? if so how to get rid of black back ground please?

thank you

first you need this node setup

then go to Blender Game, and set this to Alpha Blender (very strange but it works)
then set it back to cycles. alpha will now work in the 3D viewport, but only in Material View.

thanks so much. found a (much easier I think) way, add images as planes then when importing, bottom left check use alpha, then when back in blender, hey presto, view using materials and its all keyed out with no black background. and I just checked the node pane and it gives you the same layout as yours above :slight_smile:
