Unified Skin has incorrect anatomy

ZBrush Usage Questions
#1

I’ve created a Zsketch for a quadruped character, for which I’d now like to create a Unified Skin. However, it keeps ending up with significant anatomy errors, particularly around the tails and ears (which are very large). Parts of the legs also seem to be missing.

The Zsketch:

Results of Unified Skin:

This is the best result I able to achieve after changing the settings many times. I’m aware of the option of using an Adaptive Skin, but a solution to this problem with the Unified Skin would be better- I’d really like to know how to avoid the issue in future. Does anyone have any suggestions?

(ZBrush 4R6, Windows 7 64-bit, Zsketch has 18,000 active points)

I’ve managed a partial solution by using Unify in the Deformation subpalette. It shrunk the Zsketch down to a dot, and trying the Unified Skin on it in this state produced this:

It has some jags around the edges of the tails and ears, but it’s quite close to satisfactory. I used the manual deformation tools to scale it back up again afterwards. Can I improve it any further?

Do you really need the resolution so high? You might get better results if you lowered the resolution and the Smooth slider value.

#4

Improvement is usually possible. :wink: With practice things get easier. Is there any particular reason you haven’t upgraded to 4R7 yet? The ZModeler brush is a wonderful tool.

(Doug: You’re right, I should definitely upgrade. I hope Zbrush 5 comes out soon, I’m reeeeally looking forward to it! :D)

Having less than the max resolution was resulting in little more than a shapeless blob. :stuck_out_tongue: The above pics are my best results after many attempts with a variety of settings.

I’m more or less satisfied with the accuracy in the last pic, but I’d really like to know what caused this problem with the lost/incorrect detail. Especially if I’m going to potentially be doing more complicated sculpts in future… :frowning:
