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?
