   Totally agree... very very handy sum up to share to colegues who might wonder on the great potential of blender!

   I do have a question that I may have to do elsewhere.... I give it a try:

   I'm trying to make an animated UV projection from the camera view. That is, with a camera that is animated I'd like to project from it at its position on every frame.

   I might be approaching the problem the wrong way... but basically I have tracked a camera from a clip and now I'd like to project that same clip onto a plane corresponding to the floor of my tracked clip.

   Hints?

   Thanks in advance!

     One way to do it is to use a 'window' texture coordinate input. It's in Input -> Texture Coordinate -> Window (below Camera above Reflection). This will project the image or image sequence onto that geometry depending on how the plane is viewed, meaning that if you have a good 3D track it should line up for the whole animation pretty well.

   Hello Tim.

   Thanks! It works like a charm! I ended up testing nodes and parameters a ending up using exactly the same solution you metion... so I'm glad I've arrived to it by my self and to have someone backing up the solution!

   Cheers
