That’s the goal yes, we’re hoping to have a full pipeline inside the editor so you only need to author your geo and a simulation mesh as normal geometry in your DCC package and handle everything else in editor 
The gradient tool is a little hidden at the moment, but I’m working on it! To get it to work you need to set your begin and end values, then you can select some verts that should turn green (you can check the regular brush box if you want to paint your start selection instead of picking one by one). These green verts are your “start” verts for the gradient and will be given the starting value. Then hit return/enter, will change your brush to select red “end” verts that will be given the end value. Finally hit return/enter again and it will apply the gradient with all unselected verts being correctly interpolated between the selected values.
I’m working on better messaging and making the selection of start/end verts depend on a modifier key (probably ctrl as default) for the final tool.
Hope everyone is enjoying the tools so far, exited to get finished and out of experimental so it can be used by more people - any feedback you have is appreciated!
