Problem with Zspheres II and Retopologize

Hi guys,

I have been experimenting with Zspheres II, but ran into the following problem.

I created some basic shapes with the spheres and now want to retopologize the topology, but as soon as I hit preview, my mesh gets distorted and no matter how much I play with the settings it doesn’t seem to make any change at all, even if I turn off “Projection”, it still gets distorted.

I attached an example of this

Any suggestions would be appreciated.

Zsphere projects have always been odd. Instead of projecting the mesh directly from the adaptive skin preview try to make the mesh an adaptive skin and use the project all button in the subtool palette.

Firstly, I would recommend making your Zsketch into a skin first, and retopologising on that, not directly on the Zsketch. That seems like bad mojo.

Secondly, in the topology palette, try setting your Max strip length to 4. I've been getting some wonky results in 3.5 with higher settings when Zbrush tries to make guesses about how to fill in geo.

Thirdly, if I’m understanding what you’re doing there, projection probably isnt really necessary to mess with in this case. It seems like a fairly simple contour that your new geometry is capturing well enough. I may not be getting what you’re doing though.

Thanks goast666 and Bingo_Jackson, I just came back from a long trip, going to get some sleep and then I will give your suggestions a try.

I will give you feedback on this later.

Ok guys, I converted to skin and tried retopologizing again without any success, some areas work some don’t. I worked around this by exporting the skin to maya and using nex to retopologize, once that was done I imported the new mesh to zbrush, appended it to the skin, subdivided it 5 times and hit “Project All”, which worked perfectly.

Seems that zbrush isn’t quite capable of doing this flawlessly just yet.

what you just said worked from NEX is exactly how I would have projected it…except I would have built the cage in Modo or with straight retopo in Zbrush.

Good to hear that you got it working though.
