As they say-your mileage may vary- but as a near beginner in Zbrush-I am not having trouble making the Dawn mesh not look like Dawn. I've not played with the Grey Blob in Zbrush- just V4 and M4. I've been able to make her into everything from a Gecko Alien to a cute Doll faced Elf, to a surreal Forest Demoness Guardian-a Little Green Woman Alien, etc. It may be that this would have been easier with Genesis-but I use Poser-rather than Daz Studio for a host of reasons. I gave Genesis in Poser a Workout-but ultimately, the extra time and limitations have left her unused for many months. I can and have made plenty of Morphs for V4 and I use her in her Weight Mapped version. The Texture Converter (Blacksmith3D stand alone) works quite well-except for the eyes on some V4 textures.That may have been corrected or improved-but I've not updated since the initial release.

Here is a somewhat more feminine looking Dawn I made in Zbrush-using a Texture "Danger Lady" V4 from Odnajdy.
