Questions & Troubleshooting / Re: Hats!
« on: June 10, 2013, 08:15:04 PM »
this is one way that might work:
1) make head and hat as separate objects. The hat needs to be a discrete object, with some thickness, that is roughly in the right position (ie there might be a gap but it can't be too big) ((see first image))
2) select the head object, then go to the 'Actions' menu (in the windows/osx menu bars, not the action bar attached to the 3D window) and select "Set as Target"
3) select the hat object, switch to the VolBrush, and select the "Attract" brush (it has the magnet in the icon)
4) now when you apply the brush, the hat will be pulled towards the target (head) in the brush region. When you are done, use Clear Target to get your head back.
It may take some experimentation to get this to look right. I did this quickly and with a trackpad, so it looks pretty terrible, but you can get a much cleaner result by being careful with the brush size (essentially, by going slowly).
The pulling towards the head probably will not go in the right direction all the time, so you will need to alternate with brushes to push things into roughly the right spots. If your hat has a 'flat' botton you can combine with plane cuts.
If there is a hard edge you want to preserve, one thing you can do is use Separate to break the hat into pieces, and then enable 'Hold Boundary' in the VolumeBrush, then the boundary loop will stay put (although it may not go back together again...). This is shown in my third image.
