Hi all
I made a pyramid and inverted a mask at bottem to increase polycount there to reduce jaggies a bit.In first image jaggies
are on left, hopefully you can see em in the included pix.
I hit divide under deformations.
My pyramid did this (Like Wow Man)60`S thing. (See below)
So how do get around this and increase poly count. 
almost reminds me of the zebra renderer in the demo
Did you CLEAR the mask after you divided it? This looks like the mask is still active. You shouldn’t see this after the mask is cleared and if you do see distortion after dividing you can SMOOTH it.
I’m with mentat. That’s what happens when you divide the mesh. The mask displays the change in pixel count by variating in width and white lines. Just hit clear mask and your good to go.
Hi Digital Daydreams,
Just more info to what’s been said:
As Kruzr notes, when you do a divide the division “bleeds” outside of the masked area this is because ZB objects are not allowed to have any “T” intersections between polygons. There is a way however to avoid this “bleed”.
If before dividing you export your tool as an .obj file - then re-import this .obj file you can do a divide and only the unmasked portions will be divided - there will not be any “bleed”.
Happy modeling,
jd
The amount of great info at this forum is amazing.
Thanks for all the replies,and (Impending)
for that export import info,a new trick up my sleeve.
I`m a very happy zbrusher.
