Hiho,
I was annoyed by the fact that a camera projection does not update in the viewport when you move the projection cam around - it will only render correctly.
Now I found kind of a workaround for this issue which I would like to share but ask at the same time if there is a better method, because right now it's mighty messy.
this workaround forces maya to update the projection when the cam is moved:
-get the transform node of the projection cam and the file texture of the projection in the hypershade
-get a multiply/divide node, let it set to multiply
- wire the camera translation with input1 and set input2 to 0
-now wire the output of the multiply node to an input of the file node which can be set to 0 for your project - in my case this was "noise uv"
unfortunately the projection will not automatically update if you change the underlying geometry - maybe this can be done in a similar way?
