I’m new to CG. I purchased ZBrush 3.5 r3, and I’m just starting to learn. I’m trying to determine whether ZSketch is the best way to go to create posable models. I’ve read that ZSketch defaults to a unified skin but a posable model requires an adaptive skin. (I understand the basic distinction between unified and adaptive, although I have no clue as to why one would be posable and the other wouldn’t.)
I did find the following post in the forum:
When using ZSketch you can either apply the sketch as an Unified Skin or an Adaptive Skin. What will happen is the ZSphere geo of an adaptive skin will be used and the ZSketch will be projected into that. The thing to remember is projection works locally by ZSphere. If your rig of ZSphere is not large enough to capture the ZSketch then you will have flat projections. All you have to do is enlarge your ZShpere rig. (Not the sketch.) Here would be the steps.
1. Create a normal ZSphere rig/or armature
2. ZSketch on that rig
3. Turn off the edit Sketch
4. Turn on ShowSketch
5. You will now see your original rig with the ZSketch in Ghost Transparency mode.
6. When you click “A” now it will use the rig to create the topology but project the ZSketch into that.
7. Remember if you get flat area in certain parts then you just have to enlarge the closest ZSphere rig near that ZSketch part. You may also have to add some ZSphere in places.
I have no clue as to what is meant by “the ZSphere geo of an adaptive skin will be used and the ZSketch will be projected into that” but I tried it, using the simplest ZSphere arrangement. I noticed that when I bind the ZSketch to the ZSphere armature, then move the armature, the ZSketch (skin) “tears” at the point where the armature bends. See image:
ATT=187372
However, that does not happen with the adaptive skin. Problem is, I don’t even know what I’m looking at. I thought the ZSketch would become the adaptive skin.
If anyone can help me gain a basic understanding of the relation between (1) ability to pose a model, (2) ZSphere armature, (3) adaptive skin, and (4) the ZSketch drawn over the armature, I would really appreciate it. Is my best bet to just stay with the regular ZSphere method and forget ZSketch?
Many thanks,
