Well, clamping cuts everything outside the range of the texture, so this
behavious is expected, but I'm not sure about the reason for this
feature, probably some sort of optimization in case you don't need
unclamped values. I'm pretty sure it was there in earlier versions as
well. When you map something as absolute UV's this wont occur, but if
you tile your textures or go outside the range [0..1] in your UV
coordinates this will happen. Guess it's one of those things you gotta
keep in mind while working with shaders.

Thanks Arvid, that worked, though it doesn't explain why the xy
projection covering the whole object, just rendered in the corner. I
ended up deleting all texture-supports and projections and applying
new ones. I had another similar object with no visible bumpmap, and
when I un-checked clamp, hay-presto there it was.
I've got to say, we're experiencing lots of little 'issues' with 5,
that we didn't have with 4.2

Hi All,
Sorry for the attachment. We have a bumpmap problem.
Here's a default cylinder, subdivisions 50,100,2. noIcon textured
x,y with a bumpmap generator node. Nothings been scaled or moved.
Anyone know why it renders down there?
Cheers
Chris
