perlin noise has a horizontal stretch, but no vertical, unless you rotate and then you lose the horizontal. it strikes me that it could use both a horizontal and vertical stretch.

this may also apply to other components.

At the same time? smile:eek:

That would be the equivalent of non-uniformly scaling the noise (and break the seamless tiling possibly).

umm, no, not at the same time. one slider for each.

Just set the angle for 90* (in the Perlin Noise module), that's vertical then. Unless I'm misunderstanding what yer after. smile:)

I believe one way to think of this is that increasing the scale increases both the vertical and horizontal stretches equally.
Then if you want more width (or height) stretch then adjust the angle accordingly and add stretch... So you can get any height to width ratio you want.

I suppose if you are totally in love with a specific perlin noise pattern and the angle adjustment for some reason ruins things (which is probably (very) rare), you can then use offsets and with profile gradients to add stretches too. (But it is a bit complicated I suppose...)

(I wouldn't complain if such a feature existed, it's just that I see it as unessential.)

ok, guys, i know i can do this with two perlins. i'd just like to do it with one, but have sliders for the horizontal and the vertical in one place. sometimes i want to stretch in both directions. and yes, i could use the magnify of an offset or a frame, but that's an extra component also. it makes perfect sense to me that if you can stretch in one direction, then you could stretch in both directions.

but, it's not a biggie and as you've pointed out, it can be done elsewise. just more convenient if it were all in one place.
