Voxel Questions

I am trying to make a inv full of tools from voxel. I understand the /btool concept, I currently have /btool assign arrow Erode on a snowball, my question is, how do I now alter things like the brush size and voxel material/replace material of this brush

TY S-M-R-T people :D

(Also, if anyone has a list of toolid's it would be much appreciated :D)

 

Try here http://kraftzone.net/wiki/VoxelSniper

Its a list of all the commands and how to use Voxelsniper.

 

That was the site I was using I was using, but it doesn't talk about btool's commands to change stuff like that, nor does it have a list of the toolid's that I saw. I will look into the links on that page and all the videos though, as I never looked into those as I didn't require them to understand the voxel that I needed
