Just to add to what Francois said; if you put the mouse over the camera
projection op you'll see a tooltip that tells where the op is reading from. To
have it read after deformations drag it onto the topmost op in the construction
history/stack.
All should be good...

Hi Morten,
Something did change with camera projections in v4 but it shouldn't give you
any problems. What has changed is that when you apply it on a lowrez flat grid
(XZ) in perspective, the explicit projection is no longer distorted.
Simple setup.
in v3.51 in v4.0
That being said, editing the UVs in the texture editor shouldn't be any
different, but under the hood, the way UVs are processed is different. Of
course, these changes only work when rendering, OGL texture display doesn't
show the projection accurately.
The image you sent looks like a projection that has been applied before some
modeling was done on the object. If you move the texture operator to the top of
the object's stack, does it do any good?

well known to me.
Anybody know if its broken? - Or if something has changed radically in V4
with camera projections?
