Hi,
Dont know if i posted in the right forum but, some one will know the answer.
I start with zSpheres then make an adaptive skin, then start modelling up through the Sub divides… but i keep getting these creases showing up like its not one shape. see photo, is there some setting i need to turn on?
Thanks

You have intersecting polygons due to poor placement of the ZSpheres. See here: http://www.zbrushcentral.com/showthread.php?t=91
Hey the link was dead on that page, so when im using zspheres im making two parents?
You either have two children coming from the same “side” of the parent, or you have two ZSpheres that are too close together. Either will produce creases. At a guess from your image (because you didn’t show the ZSpheres), I think in your case it’s the latter.
