I need the numbers the most, so it could output an array. It can then be converted into heightmap or something by another plugin, while the noise itself could be used for [u:2gzx4igw]procedural generation of dungeons, caves, celestial features[/u:2gzx4igw] et cetera.
An example of texture could be background image (a nebula, stars etc.), that is randomly generated each time you visit a new star (yes, I have space exploration game in mind as well). Hopefully a seed can be preserved to regenerate the same noise on demand.
Why not just let the user decide what output he wants? In properties, he'd choose either numeric output in form of array (export numbers into an existing Array object?) or an image (with a few settings such as colors, grayscale, alpha etc., export into a Sprite object?).
Knowing the difficulty of above implementation, I'd be perfectly happy with numeric output only.
P.S.: There is a number of functions that are quite a boon in game development that would expand Construct's feature light in a positive way.
