This is a warning
A week ago i downloaded content from ShareCG.com called Victoria 5.1, after installing (by coppying the files in place) all models (including the default genesis model) had boobs and very large pointed nipples.
It took me some time to find the problem. I found it In the Parameters / Actors pannel. There was a controll added called V5.1. This controll got to max at all load or merge of a model.
I had a look at te original downloaded files to find witch files where added with this content, and deleted them from the folowing paths
\My Library\data\DAZ 3D\Genesis\Base\Morphs\Marcius Hess (delete folder Marcius Hess)
\My Library\People\Genesis\Characters\Marcius Hess\ (delete folder Marcius Hess)
Today i found the same content package on ShareCG under the name of Genesis 5.1,
So be warned to use these content packages or else above is the solution to get rid of the problem.
