A small update on the tools front:
The code below will reverse the direction of the fibers ( I don't think it actually matters at this point ).
But to keep things consistent I am keeping black as the origin and white as the insertion. The following code will just reverse the colors on the endPoints attribute.
import zCopyWeights
zCopyWeights.reverseFiberDirectionFromSelection()
Another things I found usefull is to be able to transfer maps between different nodes. An example is if the fiber weights are already painted you might want to create a material layer with that fiber map. The following code will fire up a UI that will allow you to transfer maps and reverse the values of needed.
import zCopyWeights.ui
zCopyWeights.ui.show()
Been making some progress on the sim side as well. Will hopefully have time to sim some frames and post some gifs tomorrow.
