This is great! i have been messing with it a bit and its pretty easy to use.
This may be a total noob question but how do i scale the frequency of the random node? The values in there seem to be for strength instead of size or the swirls. Also, is there some way we can generate our own equations for noise styles such as perlin, simplex etc?
I did have a few minor suggestions too, sorry if these have already been mentioned somewhere. Take it with a grain of salt
A box select option for the nodes would be great.
The linking of nodes could be improved a bit. The ability to just click on an output and then click on another input to link them (houdini style) would be very helpful instead of having to click and drag.
The area you need to click to connect 2 nodes is a bit small. If the node has only one input it would be nice if you could just click the input node and have it link up instead of having to precisely drag it over top of the dot.
This is sort of a personal preference thing but it wold be awesome of the panning of the node graph was on middle click instead of left click, for consistency with other programs. (selectable option perhaps)
A tileable option would be nice as well. Not just making the vector field tile able but also being able to infinitely tile it in the display window.
The ability load, modify and convert vector fields from houdini/fumefx into fga.
