[sldev] Re: New Sculpty Features

[Karl Stiefvater]

it depends on what end-result you're trying to achieve.

if you just want the prim to have the same visual appearance as if the  
y and z channels were swapped, you can achieve the same thing turning  
on MIRROR and rotating the prim 90 degrees.

the reasoning for these two new flags is that they give a substantial  
advantage.  MIRROR gives you (without the need of a second map) a  
symmetric shape  (e.g. shoes.)  INVERT will give you a backside to  
your planar sculpts.  in both cases - the number of necessary sculpt  
maps is reduced.

offhand, i don't see the advantage of swapping two channels.  couldn't  
you just re-generate the sculpt map?
